Influence of Anesthesiology Protocol on the Quality of Intraoperative Nerve Monitoring During Thyroid Surgery, One-Year Single Center Experience.

Anesthesia plays a very important role in the successful management of intraoperative neuromonitoring (IONM). The aim of our study was to investigate the impact of anesthesia induction and maintenance on the quality of signals during surgeries on the thyroid and parathyroid glands using neuromonitoring. The study included 72 patients who underwent surgery with IONM for one year. All the patients were intubated using a Glidescope videolaryngoscope with a hyperangulated blade. Two different approaches were used to facilitate intubation: succinylcholine-1 mg/kg and rocuronium bromide-0.3 mg/kg. For anesthesia maintenance, total intravenous anesthesia (TIVA) or combined anesthesia was used. Patients' body movements during operations, as well as electromyography signals from the vagus and recurrent laryngeal nerves before resection, were recorded as V1 and R1. Intraoperative unwanted movements were recorded in 25% of patients. Undesired movements were more frequently recorded in the TIVA group compared to the combined anesthesia group (p < 0.001) as well as in patients who received succinylcholine compared to patients who received rocuronium bromide (p = 0.028). Type of anesthesia maintenance as well as type of muscle relaxant did not affect the quality of recorded nerve signals. (p = 0.169 and p = 0.894, respectively). The type of muscle relaxant used significantly affects the occurrence of undesirable movements during thyroid surgery with IONM, while the type of anesthesia maintenance did not influence either the quality of the obtained signal or the occurrence of undesirable movements.

Quality of Recovery in Pediatrics After Tonsillectomy Under Total Intravenous Anesthesia Versus Sevoflurane Anesthesia

Introduction: Inhalational anesthetics are often the first choice in pediatric anesthesia. However, the most recent literature demonstrates possible advantages of total intravenous anesthesia (TIVA). The goal of this study was to compare the postoperative quality in children submitted to tonsillectomy under TIVA versus sevoflurane anesthesia. Materials and Methods: Prospective observational case-control study (Sevoflurane vs TIVA) including children submitted to (adeno) tonsillectomy to compare the quality of anesthesia considering intra and postoperative parameters. Data was collected from clinical records, anesthetic monitoring and interviews. Results: From the 52 children included, 25% received TIVA. TIVA group had a shorter time for liquid diet reintroduction (42 minutes vs. 95 minutes) (p&lt;0.05) and the Sevoflurane group had a lower mean blood pressure variation (p=0.027). Mean wake up time was similar for both groups (11.3±6.2 minutes for TIVA and 11.6±5.3 minutes for Sevoflurane). In PACU, TIVA group demonstrated, although not statistically significant, a shorter time of stay (40 minutes vs. 41 minutes), less emergence delirium (7.7% vs. 12.5%) and less nausea and vomiting (0% vs. 5.1%). At 24 hours, TIVA group presented, although not statistically significant, less nausea and vomiting (7.7% vs 13.5%), lower pain (69.2% with &lt;5 on the numerical pain scale vs 56.8%) and higher parental satisfaction (10 vs 8). Conclusion: This study suggests that TIVA for tonsillectomy may be associated with better recovery quality. However, given the limited sample size of this study, it should be repeated in a larger sample, or in a multicentric study, for more robust conclusions.

Comparison of postoperative outcomes after cranial neurosurgery using propofol-based total intravenous anesthesia versus inhalation anesthesia: a nationwide cohort study in South Korea.

We aimed to determine whether propofol-based total intravenous anesthesia (TIVA) is associated with mortality and morbidity following cranial neurosurgery compared with inhalation anesthesia. This nationwide, retrospective, population-based cohort study included patients who underwent cranial neurosurgery under general anesthesia between January 1, 2016, and December 31, 2021. The two study endpoints were 90-day mortality and postoperative complications. In total, 144,506 adult patients were included: 65,442 patients (45.3%) who received TIVA (TIVA group) and 79,064 (54.7%) who received inhalation anesthesia (inhalation anesthesia group). After propensity score (PS) matching, 97,156 patients (48,578 in each group) were included. The 90-day mortality rates after cranial neurosurgery were 14.0% (6,660 / 48,578) in the TIVA group and 14.2% (6,779 / 48,578) in the inhalation anesthesia group. Moreover, the postoperative complication rates following cranial neurosurgery were 47.1% (22,411 / 48,578) and 50.3% (23,912 / 48,578) in the TIVA and inhalation anesthesia groups, respectively. Based on the logistic regression analysis, TIVA was not associated with 90-day mortality compared with inhalation anesthesia (odds ratio [OR]: 0.97, 95% CI: 0.94, 1.01; P = 0.188) in the PS-matched cohort. Logistic regression analysis revealed that the TIVA group had a 12% (OR: 0.88, 95% CI: 0.86, 0.90; P < 0.0.001) lower postoperative complication rate than the inhalation anesthesia group. There was no significant association between the type of anesthesia and postoperative 90-day mortality in patients who underwent cranial neurosurgery in South Korea. However, propofol-based TIVA was associated with a lower incidence of postoperative complications than inhalation anesthesia.

Comparison of Total Intravenous Anesthesia with Inhaler Anesthesia in Children Intubated with Remifentanil without Muscle Relaxant

Objective: The effects of remifentanil and muscle relaxant-free intubation as well as total intravenous anesthesia and inhaled anesthesia for tonsillectomy and/or adenoidectomy in children were compared. Materials and Methods: The study was conducted on 80 patients who were to undergo tonsillectomy and/or adenoidectomy between December 2014 and June 2015. Patients were randomized and divided into two groups. In the total intravenous anaesthesia group, 2.5 mg/kg propofol and 2 mcg/kg remifentanil were administered as induction within 90 seconds. In this group, 3 mg/kg/h propofol and 0.5 mcg/kg/min remifentanil were used for maintenance of anesthesia. In the sevoflurane group, 8% sevoflurane and 2 mcg/kg remifentanil were administered as induction within 90 seconds. In this group, 2.5% sevoflurane, 50% nitrogen protoxide and 50% oxygen were used at 6 l/min for maintenance of anesthesia. Results: Peak heart rate and systolic arterial pressure were significantly higher in Group I. Diastolic arterial pressure was significantly higher in Group T at 1 and 2 minutes after intubation and in Group 2 at 10 minutes postoperatively. Mean arterial pressure was higher in Group T at 2 minutes after intubation. In addition, Wong-Baker pain scale and agitation score were significantly higher in Group I. Spontaneous respiration and extubation time were significantly shorter in Group I. There was no difference between the groups in terms of side effects. Conclusion: Group total intravenous anaesthesia was thought to be a better choice in children because it had less impact on postoperative pain, agitation and recovery.

Recurrence-free survival after curative resection of non-small cell lung cancer between inhalational gas anesthesia and propofol-based total intravenous anesthesia: a multicenter, randomized, clinical trial (GAS TIVA trial): protocol description

BackgroundSurgery is the primary treatment for non-small cell lung cancer (NSCLC), but microscopic residual disease may be unavoidable. Preclinical studies have shown that volatile anesthetics might suppress host immunity and promote a pro-malignant environment that supports cancer cell proliferation, migration, and angiogenesis, whereas propofol may preserve cell-mediated immunity and inhibit tumor angiogenesis. However, clinical evidence that propofol-based total intravenous anesthesia (TIVA) can reduce tumor recurrence after curative resection remains inconsistent due to the retrospective observational nature of previous studies. Therefore, we will test the hypothesis that the recurrence-free survival (RFS) after curative resection of NSCLC is higher in patients who received TIVA than volatile anesthetics (GAS) in this multicenter randomized trial.MethodsThis double-blind, randomized trial will enroll patients at 22 international sites, subject to study registration, institutional review board approval, and patient written informed consent. Eligible patients are adult patients undergoing lung resection surgery with curative intent for NSCLC. Exclusion criteria will be contraindications to study drugs, American Society of Anesthesiologists physical status IV or higher, or preexisting distant metastasis or malignant tumor in other organs. At each study site, enrolled subjects will be randomly allocated into the TIVA and GAS groups with a 1:1 ratio. This pragmatic trial does not standardize any aspect of patient care. However, potential confounders will be balanced between the study arms. The primary outcome will be RFS. Secondary outcomes will be overall survival and complications within postoperative 7 days. Enrollment of 5384 patients will provide 80% power to detect a 3% treatment effect (hazard ratio of 0.83) at alpha 0.05 for RFS at 3 years.DiscussionConfirmation of the study hypothesis would demonstrate that a relatively minor and low-cost alteration in anesthetic management has the potential to reduce cancer recurrence risk in NSCLC, an ultimately fatal complication. Rejection of the hypothesis would end the ongoing debate about the relationship between cancer recurrence and anesthetic management.Trial registrationThe study protocol was prospectively registered at the Clinical trials (https://clinicaltrials.gov, NCT06330038, principal investigator: Hyun Joo Ahn; date of first public release: March 25, 2024) before the recruitment of the first participant.

Impact of general anesthesia on postoperative complications in orthognathic surgery: a retrospective comparison of total intravenous anesthesia versus volatile anesthesia

Orthognathic surgery has a high incidence of postoperative nausea (PON) and vomiting (POV), delaying mobility initiation and postoperative recovery. Bleeding is another risk associated with this surgical procedure. We aimed to compare total intravenous anesthesia (TIVA) and volatile anesthesia in patients undergoing orthognathic surgery in terms of postoperative nausea and vomiting (PONV) incidence and hemodynamic changes. This retrospective study included 82 patients who underwent bilateral sagittal split ramus osteotomies at Saga University Hospital between April 2016 and April 2021. We compared the effects of TIVA and volatile anesthesia on PONV onset after surgery, acute postoperative hemodynamic changes (blood pressure and heart rate), and factors contributing to PONV. PON was significantly lower in the TIVA group than in the volatile anesthesia group. The total dose of fentanyl contributed to the onset of POV, while the onset of PON was associated with low volumes of fluid infusion and urine in the TIVA and volatile anesthesia groups, respectively. Furthermore, post-extubation hemodynamic change was significantly smaller in the TIVA group than in the volatile anesthesia group. Therefore, TIVA could have a reduced risk of PONV and hemodynamic changes in patients undergoing orthognathic surgery. Employing TIVA could mitigate perioperative complications and enhance patient safety.

Propofol total intravenous anesthesia vs. sevoflurane inhalation anesthesia: Effects on post‑operative cognitive dysfunction and inflammation in geriatric patients undergoing laparoscopic surgery.

Propofol total intravenous anesthesia (TIVA) or sevoflurane inhalation anesthesia (IA) affects post-operative cognitive dysfunction in geriatric patients undergoing laparoscopic surgery; however, relevant real-world clinical evidence on the matter is limited. The present study aimed to compare the effects of propofol TIVA and sevoflurane IA on post-operative cognitive dysfunction in the aforementioned type of patients. The present prospective study enrolled 197 geriatric patients undergoing laparoscopic surgery. Patients were assigned to the propofol TIVA group (n=97) and sevoflurane IA group (n=100) according to the actual anesthesia regimens. The mini-mental state examination (MMSE) score was assessed before surgery and on day (D)1, D3 and D7 following surgery in both groups. The MMSE score on D1 was higher in the TIVA group compared with the IA group (P=0.006). The change in the MMSE scores from before surgery to D1 (P<0.001), D3 (P=0.011) and D7 (P=0.003) was smaller in the TIVA group vs. the IA group. Multivariate linear regression analyses suggested that the anesthesia method of TIVA (vs. IA) was independently related to the increased MMSE score on D1 (b=0.803; P=0.001) and D7 (b=0.472; P=0.025). The levels of interleukin (IL)-17A, IL-6 and tumor necrosis factor-α on D1, D3 and D7 exhibited a slightly decreasing trend in the TIVA group vs. the IA group, although the difference was not statistically significant (all P>0.05). Notably, the levels of IL-17A before surgery (P=0.015), on D3 (P=0.016) and D7 (P=0.002), as well as those of IL-6 on D1 (P=0.027), were negatively associated with the MMSE score at the corresponding time points. Overall, the present study demonstrates that propofol TIVA ameliorates post-operative cognitive dysfunction on D1 compared with sevoflurane IA and exerts a potentially suppressive effect on inflammation in geriatric patients undergoing laparoscopic surgery.

Effect of converting from propofol to remimazolam with flumazenil reversal on recovery from anesthesia in outpatients with mental disabilities: a randomized controlled trial

BackgroundGeneral anesthesia is often necessary for dental treatment of outpatients with mental disabilities. Rapid recovery and effective management of postoperative nausea and vomiting (PONV) are critical for outpatients. This study aimed to investigate the effect of transitioning from propofol to remimazolam with flumazenil reversal administered toward the end of surgery during propofol-based total intravenous anesthesia (TIVA) on recovery.MethodsAdults with mental disabilities scheduled to undergo dental treatment were randomly assigned to receive either propofol-based TIVA (Group P) or propofol-remimazolam-based TIVA with flumazenil reversal (Group PR). Propofol was replaced with remimazolam 1 h before the end of surgery in Group PR; moreover, 0.5 mg of flumazenil was administered after the neuromuscular blockade reversal agent. The primary outcome was the duration of stay in the post-anesthesia care unit (PACU). The secondary outcomes included time to eye-opening, time to extubation, occurrence of PONV, and quality of recovery.ResultsFifty-four patients were included in this study. The duration of stay in the PACU in Group PR was significantly shorter than that in Group P (mean difference, 8.7 min; confidence interval [95% CI], 3.3–14.2; P = 0.002). Group PR exhibited a shorter time to eye opening (mean difference, 5.4 min; 95% CI, 3.3–8.1; P < 0.001) and time to extubation (mean difference, 5.5 min; 95% CI, 3.6–7.9; P < 0.001) than Group P. Neither group required the administration of rescue analgesics, and the incidence of PONV was not reported.ConclusionsTransitioning from propofol to remimazolam 1 h before the end of surgery followed by flumazenil reversal reduced the duration of stay in the PACU and the time to eye opening and extubation without affecting the incidence of PONV and quality of recovery.Trial registration numberClinical Research Information Service (KCT0007794), Clinical trial first registration date: 12/10/2022.

Comparison of the Effects of Inhalational Anesthesia with Sevoflurane and Total Intravenous Anesthesia in Open Heart Surgery

Background: The primary objective of this study was to compare sevoflurane inhalation anesthesia with total intravenous anesthesia (TIVA) in terms of its effectiveness in maintaining adequate depth of anesthesia during all open heart surgery procedures, including cardiopulmonary bypass. The study's secondary objective was to compare sevoflurane inhalation anesthesia with TIVA regarding the impact on the time of tracheal extubation and the incidence of postoperative acute kidney injury during open heart surgeries. Methods: A total of 58 patients undergoing open heart surgery were included, with 30 receiving sevoflurane inhalation anesthesia and 28 receiving TIVA. Demographic characteristics, intraoperative parameters, and postoperative outcomes were recorded and analyzed. Statistical analysis revealed no significant differences in Bispectral Index (BIS) monitor values, mean arterial pressure, body temperature, or other intraoperative parameters between the two groups. Notably, the time to tracheal extubation was significantly shorter in the Sevoflurane group compared to the TIVA group, although both groups exhibited similar rates of postoperative acute kidney injury (AKI). Results: None of the patients had complaints of intraoperative awareness. The mean arterial pressure, body temperature, and bispectral index values during and before cardiopulmonary bypass were similar between the groups. Postoperative variables such as intensive care unit stay duration, incidence of acute kidney injury, and immediate and 24-hour post-extubation visual analog scale values were similar between the groups. The tracheal extubation time was found to be statistically shorter in the sevoflurane group. Conclusion: We believe that sevoflurane inhalation anesthesia can achieve adequate depth of anesthesia during the intraoperative period in open heart surgery without increasing the rate of postoperative complications.

Comparison of combined intravenous and inhalation anesthesia and total intravenous anesthesia in laparoscopic surgery and the identification of predictive factors influencing the delayed recovery of neurocognitive function.

Compare the anesthesia effects of combined intravenous and inhalation anesthesia (CIVIA) and total intravenous anesthesia (TIVA) in laparoscopic surgery. Furthermore, our objective is to examine the elements that contribute to the delay in postoperative recovery of neurocognitive function and anticipate the manifestation of delayed recovery by analyzing serum cytokines. The CIVIA group and the TIVA group both consisted of 130 patients who were scheduled to have elective major abdominal surgery through laparoscopy. The criteria taken into account by the observational and record-keeping study were the patients' ages, sexes, body masses, heights, and the presence or absence of any preexisting problems. Both groups also had their anesthetic depth, duration, and per-unit-of-time muscle relaxant and analgesic dosages recorded. Finally, the length of each patient's stay in the hospital as well as their overall length of stay were tracked. By using the Mini-Mental State Examination (MMSE) to measure cognitive function, we assessed the mental states of the subjects. Additionally, we wanted to identify any biomarkers that could be linked to postoperative cognitive decline or delays in neurocognitive recovery. A total of 51 participants from the CIVIA group and 53 participants from the TIVA group satisfactorily completed the necessary neuropsychological exam for identifying delayed neurocognitive recovery at the study's completion. In the initial data of the two groups, no significant discrepancies were found (p > 0.05). The CIVIA group exhibited noteworthy reductions in the quantity of administered analgesics and muscle relaxants per unit of time in comparison to the TIVA group (p < 0.05). In addition to this, the duration from the sevoflurane tank being closed to the extubation period demonstrated a significant reduction in the CIVIA group compared to the TIVA group (p < 0.05). Moreover, no statistically notable distinction was observed in terms of postoperative hospitalization duration and overall hospitalization duration among both groups (p > 0.05). According to the study, both the CIVIA group and the TIVA group had a total of 7 (13.72%) and 17 (32.07%) individuals, respectively, who met the criteria for neurocognitive delayed recovery (Odds Ratio: 0.336; 95% CI: 0.134-0.864; p = 0.026). According to the research findings, it is indicated that there is a possibility for an increased presence of IL-6 in the bloodstream within 60 min following the incision made on the skin. This occurrence subsequently leads to the prolonged restoration of neurocognitive capabilities. The CIVIA technique outperforms the TIVA method in terms of overall assessment in the setting of laparoscopic surgery. It's also important to remember that an increased blood IL-6 level during laparoscopy may operate as a separate risk factor for a delay in the restoration of neurocognitive function.

Comparison of the Effectiveness of Total Intravenous Anesthesia (TIVA) vs Inhalation Techniques in Patients with Morbid Obesity at Dr. M. Djamil General Hospital, Padang, Indonesia

Introduction: Morbidly obese patients (BMI ≥ 40 kg/m²) present unique challenges in anesthesia. Total intravenous anesthesia (TIVA) and inhalation techniques have their respective advantages and disadvantages in this group of patients. This study aims to compare the effectiveness and safety of TIVA and inhalation anesthesia in morbidly obese patients at Dr. M. Djamil General Hospital Padang.&#x0D; Methods: A prospective, randomized study was conducted on 80 morbidly obese patients undergoing elective surgery. Patients were randomized to receive TIVA with propofol and remifentanil or inhalation anesthesia with sevoflurane and desflurane.&#x0D; Results: The TIVA group demonstrated faster recovery time (p = 0.02) and less postoperative opioid requirements (p = 0.01) than the inhalation group. There was no significant difference in the incidence of intraoperative or postoperative complications.&#x0D; Conclusion: TIVA is an effective and safe option for morbidly obese patients undergoing elective surgery. TIVA offers faster recovery and fewer postoperative opioid requirements than inhalation anesthesia.

The impact of inhalation versus total intravenous anesthesia on the immune status in patients undergoing breast cancer surgery: a double-blind randomized clinical trial (TeMP).

Breast cancer (BC) mortality primarily stems from metastases rather than the primary tumor itself. Perioperative stress, encompassing both surgical and anesthetic factors, profoundly impacts the immune system, leading to alterations in neuroendocrine pathways and immune functions, potentially facilitating tumor progression and metastasis. Understanding the immunomodulatory effects of different anesthesia techniques is crucial for optimizing perioperative care in patients with BC. The neutrophil-to-lymphocyte ratio (NLR) serves as one of the key indicators of perioperative immune response. To compare the effects of inhalation anesthesia (IA) and total intravenous anesthesia (TIVA) on perioperative immune response in BC surgery patients. In this randomized, double-blind clinical trial, BC surgery patients were randomized to receive either TIVA with propofol or IA with sevoflurane. The primary endpoint was NLR assessment. Secondary immune parameters measured included natural killer cells, various T cell subsets, B cells, the immuno-regulatory index [T-helpers (CD3+CD4+)/cytotoxic T-cells (CD3+CD8+)], matrix metallopeptidases (MMP-9), complement components, and immunoglobulins, preoperatively and at 1 and 24 hours postoperatively. The study included 98 patients (IA: 48, TIVA: 50). The baseline characteristics exhibited remarkable similarity across the groups. No significant difference in absolute NLR values was found between IA and TIVA groups at any time point (1 hour: p = 0.519, 24 hours: p = 0.333). Decreased IgA and IgM levels post-surgery suggested potential negative impacts of IA on humoral immunity compared to TIVA. CRP levels increased more by 24 hours (p = 0.044) in IA compared to TIVA. No significant differences were observed in natural killer cells, T cell subsets, B cells, MMP-9 levels or complement components between groups. Significant differences in the immuno-regulatory index between the TIVA and IA groups at one hour postoperatively (p = 0.033) were not maintained at 24 hours. While there were no notable differences in NLR among the types of anesthesia, the observed disparities in immunoglobulin content and C-reactive protein levels between groups suggest that we cannot dismiss the potential immunosuppressive effects of inhalational anesthesia in breast cancer surgeries. Further investigation needed to clarify the impact of various anesthesia methods on immune function and their implications for long-term cancer outcomes.

Comparison of Complications between Total Intravenous Anaesthesia and Combined Intravenous and Inhalation Anaesthesia after Renal Biopsy in Children.

The objective of this study was to examine the influence of total intravenous anaesthesia (TIVA) compared to combined intravenous and inhalation anaesthesia (CIIA) in paediatric patients undergoing renal biopsy. A total of 86 children with nephrotic syndrome, acute glomerulonephritis, chronic glomerulonephritis, IgG nephropathy, systemic lupus erythematosus and purpura nephritis were selected from January 2018 to January 2023 in our hospital. All children were divided into the total intravenous anaesthesia group and intravenous inhalational anaesthesia group according to the anaesthesia method. The experimental group comprised 46 children with renal diseases who underwent static aspiration compound anaesthesia during renal biopsy at our hospital from January 2018 to January 2023. Conversely, the control group included 40 children with renal diseases who underwent total intravenous anaesthesia during renal biopsy at the hospital within the same period. Hemodynamic parameters, such as mean arterial pressure (MAP), heart rate (HR), and oxygen saturation (SPO2), were assessed at four different time points: Before anesthesia induction (T0), during anesthesia induction (T1), after anesthesia induction (T2), and at the conclusion of the surgery (T3). Puncture success rate, time to renal puncture, time to get out of bed, postoperative recovery from anaesthesia (including time to postoperative awakening and time to return to spontaneous respiration) and incidence of adverse anaesthetic reactions were also included. We observed notable variations in HR and MAP at T2 and T3, as well as SPO2 levels, duration of awakening from anaesthesia and time taken to resume spontaneous respiration between the two groups at T2 (p < 0.05). No statistically significant variances were detected between the two groups concerning adverse reactions to anaesthesia, puncture success rate, duration to renal puncture and time to mobilisation from bed (p > 0.05). In conclusion, compared with the total intravenous anaesthesia, the implementation of the sedation-aspiration-combined anaesthesia in renal biopsy in children with renal disease features less haemodynamic fluctuation, better postoperative anaesthesia recovery and does not increase the incidence of adverse reactions.

Anesthesia-related postoperative oncological surgical outcomes: a comparison of total intravenous anesthesia and volatile anesthesia. A meta-analysis.

In patients undergoing cancer surgery, it is ambiguous whether propofol-based total intravenous anesthesia (TIVA) elicits a significantly higher overall survival rate than volatile anesthetics (VA). Consequently, evaluating the impact of TIVA and VA on long-term oncological outcomes is crucial. This study compared TIVA versus VA for cancer surgery patients and investigated the potential correlation between anesthetics and their long-term surgical outcomes. A comprehensive search of Medline, EMBASE, Scopus, and Cochrane Library identified English-language peer-reviewed journal papers. The statistical measurements of hazard ratio (HR) and 95% CI were calculated. We assessed heterogeneity using Cochrane Q and I2 statistics and the appropriate p-value. The analysis used RevMan 5.3. The meta-analysis included 10 studies with 14036 cancer patients, 6264 of whom received TIVA and 7777 VA. In this study, we examined the long-term oncological outcomes of cancer surgery patients with TIVA and VA. Our data show that the TIVA group had a considerably higher overall survival rate (HR = 0.49, 95% CI: 0.30-0.80) and recurrence-free survival rate (HR = 0.56, 95% CI: 0.32-0.97). Each outcome was statistically significant (p < 0.05). The present study concludes that TIVA is a more effective anesthetic agent than VA in obtaining better long-term oncological outcomes in cancer patients after surgery as it provides a higher overall survival rate, a higher recurrence-free survival rate and fewer post-operative pathological findings in patients who have undergone surgery for cancer as compared to VA.

Inhalational Anesthesia Reduced Transient Neurological Events After Revascularization Surgery for Moyamoya Disease

BACKGROUND AND OBJECTIVES: The choice between inhalational and total intravenous anesthesia (TIVA) in revascularization surgery for Moyamoya disease (MMD) remains a topic of debate. Anesthesia methods have changed with the advent of new anesthetics. This study investigated whether modern anesthesia methods affected the development of neurological symptoms after revascularization surgery for MMD. METHODS: This single-center retrospective study included 63 adult patients (82 hemispheres) with MMD treated with direct and indirect bypass surgeries at our hospital between 2013 and 2022. Patients were divided into inhalational anesthesia (IA) and TIVA groups based on the anesthesia maintenance method. Baseline patient characteristics; postoperative neurological symptoms, including hyperperfusion syndrome, cerebral infarction, and transient neurological events (TNEs); and cortical hyperintensity belt (CHB) sign scores (5-point scale from 0 to 4) on postoperative magnetic resonance imaging were compared between the two groups. The operation methods, anesthetics, and intraoperative hemodynamic and ventilatory parameters were compared between patients with and without TNEs. RESULTS: The IA and TIVA groups comprised 39 and 43 hemispheres, respectively. The frequency of postoperative hyperperfusion syndrome and cerebral infarction did not differ between the groups, but the number of TNEs in the IA group (5/39; 13%) was significantly lower than that in the TIVA group (16/43; 37%). Multivariate logistic regression analysis revealed that TNEs were associated with TIVA (odds ratio, 3.91; 95% CI, 1.24-12.35; P = .02). The median [IQR] postoperative CHB sign score in the IA group (2 [1-3]) was significantly lower than that in the TIVA group (4 [3-4]). CONCLUSION: The IA group had fewer postoperative TNEs and lower CHB sign scores than the TIVA group. Although further studies are needed, this study provides insights into the prevention of TNEs with IA and reconsideration of the optimal anesthesia for MMD.

Total intravenous anesthesia decreases hospital stay but not incidence of postoperative pulmonary complications after lung resection surgery: a propensity score matching study

BackgroundThere is no consensus regarding the superiority of volatile or total intravenous anesthesia (TIVA) in reducing the incidence of postoperative pulmonary complications (PPCs) after lung resection surgery (LRS). Thus, the aim of this study was to investigate the different anesthetic regimens and the incidence of PPCs in patients who underwent LRS. We hypothesized that TIVA is associated with a lower incidence of PPCs than volatile anesthesia.MethodsThis was a retrospective cohort study of patients who underwent LRS at Taipei Veterans General Hospital between January 2016 and December 2020. The patients’ charts were reviewed and data on patient characteristics, perioperative features, and postoperative outcomes were extracted and analyzed. The patients were categorized into TIVA or volatile anesthesia groups and their clinical data were compared. Propensity score matching was performed to reduce potential selection bias. The primary outcome was the incidence of PPCs, whereas the secondary outcomes were the incidences of other postoperative events, such as length of hospital stay (LOS) and postoperative nausea and vomiting (PONV).ResultsA total of 392 patients each were included in the TIVA and volatile anesthesia groups. There was no statistically significant difference in the incidence of PPCs between the volatile anesthesia and TIVA groups. The TIVA group had a shorter LOS (p < 0.001) and a lower incidence of PONV than the volatile anesthesia group (4.6% in the TIVA group vs. 8.2% in the volatile anesthesia group; p = 0.041). However, there were no significant differences in reintubation, 30-day readmission, and re-operation rates between the two groups.ConclusionsThere was no significant difference between the incidence of PPCs in patients who underwent LRS under TIVA and that in patients who underwent LRS under volatile anesthesia. However, TIVA had shorter LOS and lower incidence of PONV which may be a better choice for maintenance of anesthesia in patients undergoing LRS.

Effects of propofol-based total intravenous anesthesia versus desflurane anesthesia on natural killer cell cytotoxicity after hepatocellular carcinoma resection.

Inhalation anesthesia suppresses the immune system and stimulates the growth of tumor cells, contrary to intravenous anesthesia. However, no consensus exists on which anesthetic technique is better for preventing cancer recurrence. Therefore, this study compared the effects of two different anesthetic techniques on natural killer cell cytotoxicity (NKCC) in hepatocellular carcinoma (HCC) patients undergoing open hepatic resection. Patients diagnosed with nonmetastatic HCC were scheduled for hepatic resection and randomly assigned to receive either propofol- or desflurane-based anesthesia. The primary outcome was pre- and postoperative NKCC assay. Cytokine levels were assessed by measuring interleukin (IL)-2, IL-4, IL-6, IL-10, tumor necrosis factor-alpha (TNF-α), and interferon-gamma (IFN-γ) levels, and the secondary outcome was postoperative cancer recurrence evaluated using diagnostic imaging scans for 2 years. Twenty-eight patients were analyzed, including 15 and 13 in the total intravenous anesthesia (TIVA) and inhalation (INH) groups, respectively. Two patients in the INH group were excluded due to non-HCC postoperative pathologic results. At 24 h, the postoperative change in NKCC between both groups showed no significant differences at a ratio of effector cell: target cell = 1:1, 5:1, and 10:1 (P = 0.345, 0.345, and 0.565, respectively). Also, there were no significant differences in IL-2, IL-4, IL-6, IL-10, TNF-α, and IFN-γ levels (P = 0.588, 0.182, 0.730, 0.076, 0.518, 0.533, respectively). Postoperative tumor recurrence occurred in five and six patients in the TIVA and INH groups, respectively. NKCC did not differ significantly among HCC patients undergoing open hepatic resection under either propofol or desflurane anesthesia 24 h postoperatively.

A prospective randomized study examining the impact of intravenous versus inhalational anesthesia on postoperative cognitive decline and delirium

The present prospective randomized study was designed to investigate whether the development of Post Operative Cognitive Decline (POCD) is related to anesthesia type in older adults. All patients were screened for delirium and mental status, received baseline neuropsychological assessment, and evaluation of activities of daily living (ADLs). Follow-up assessments were performed at 3-6 months and 12-18 months. Patients were randomized to receive either inhalation anesthesia (ISO) with isoflurane or total intravenous anesthesia (TIVA) with propofol for maintenance anesthesia. ISO (n = 99) and TIVA (n = 100) groups were similar in demographics, preoperative cognition, and incidence of post-operative delirium. Groups did not differ in terms of mean change in memory or executive function from baseline to follow-up. Pre-surgical cognitive function is the only variable predictive of the development of POCD. Anesthetic type was not predictive of POCD. However, ADLs were predictive of post-operative delirium development. Overall, this pilot study represents a prospective, randomized study demonstrating that when examining ISO versus TIVA for maintenance of general anesthesia, there is no significant difference in cognition between anesthetic types. There is also no difference in the occurrence of postoperative delirium. Postoperative cognitive decline was best predicted by lower baseline cognition and functional status.

Impact of total intravenous anesthesia and total inhalation anesthesia as the anesthesia maintenance approaches on blood glucose level and postoperative complications in patients with type 2 diabetes mellitus: a double-blind, randomized controlled trial

BackgroundDiabetes mellitus is a prevalent metabolic disease in the world. Previous studies have shown that anesthetics can affect perioperative blood glucose levels which related to adverse clinical outcomes. Few studies have explored the choice of general anesthetic protocol on perioperative glucose metabolism in diabetes patients. We aimed to compare total intravenous anesthesia (TIVA) with total inhalation anesthesia (TIHA) on blood glucose level and complications in type 2 diabetic patients undergoing general surgery.MethodsIn this double-blind controlled trial, 116 type 2 diabetic patients scheduled for general surgery were randomly assigned to either the TIVA group or TIHA group (n = 56 and n = 60, respectively). The blood glucose level at different time points were measured and analyzed by the repeated-measures analysis of variance. The serum insulin and cortisol levels were measured and analyzed with t-test. The incidence of complications was followed up and analyzed with chi-square test or Fisher’s exact test as appropriate. The risk factors for complications were analyzed using the logistic stepwise regression.ResultsThe blood glucose levels were higher in TIHA group than that in TIVA group at the time points of extubation, 1 and 2 h after the operation, 1 and 2 days after the operation, and were significantly higher at 1 day after the operation (10.4 ± 2.8 vs. 8.1 ± 2.1 mmol/L; P < 0.01). The postoperative insulin level was higher in TIVA group than that in TIHA group (8.9 ± 2.9 vs. 7.6 ± 2.4 IU/mL; P = 0.011). The postoperative cortisol level was higher in TIHA group than that in TIVA group (15.3 ± 4.8 vs. 12.2 ± 8.9 ug/dL ; P = 0.031). No significant difference regarding the incidence of complications between the two groups was found based on the current samples. Blood glucose level on postoperative day 1 was a risk factor for postoperative complications (OR: 1.779, 95%CI: 1.009 ~ 3.138).ConclusionsTIVA has less impact on perioperative blood glucose level and a better inhibition of cortisol release in type 2 diabetic patients compared to TIHA. A future large trial may be conducted to find the difference of complications between the two groups.Trial registrationThe protocol registered on the Chinese Clinical Trials Registry on 20/01/2020 (ChiCTR2000029247).

Randomized controlled trial of the effect of general anesthetics on postoperative recovery after minimally invasive nephrectomy.

General anesthetic techniques can affect postoperative recovery. We compared the effect of propofol-based total intravenous anesthesia (TIVA) and desflurane anesthesia on postoperative recovery. In this randomized trial, 150 patients undergoing robot-assisted or laparoscopic nephrectomy for renal cancer were randomly allocated to either the TIVA or desflurane anesthesia (DES) group. Postoperative recovery was evaluated using the Korean version of the Quality of Recovery-15 questionnaire (QoR-15K) at 24 h, 48 h, and 72 h postoperatively. A generalized estimating equation (GEE) was performed to analyze longitudinal QoR-15K data. Fentanyl consumption, pain severity, postoperative nausea and vomiting, and quality of life three weeks after discharge were also compared. Data were analyzed for 70 patients in each group. The TIVA group showed significantly higher QoR-15K scores at 24 and 48 h postoperatively (24 h: DES, 96 [77, 109] vs. TIVA, 104 [82, 117], median difference 8 [95% CI: 1, 15], P = 0.029; 48 h: 110 [95, 128] vs. 125 [109, 130], median difference 8 [95% CI: 1, 15], P = 0.022), however not at 72 h (P = 0.400). The GEE revealed significant effects of group (adjusted mean difference 6.2, 95% CI: 0.39, 12.1, P = 0.037) and time (P < 0.001) on postoperative QoR-15K scores without group-time interaction (P = 0.051). However, there were no significant differences in other outcomes, except for fentanyl consumption, within the first 24 h postoperatively. Propofol-based TIVA showed only a transient improvement in postoperative recovery than desflurane anesthesia, without significant differences in other outcomes.
