Incidence Of Postoperative Nausea Research Articles

Different dexamethasone doses in the perioperative period improve short-term outcomes of total hip arthroplasty: a randomized controlled trial.

This study aimed to evaluate the efficacy of different dexamethasone doses in the perioperative period of total hip arthroplasty (THA). We randomly divided 180 patients into three groups: three perioperative saline injections (Group A, placebo); two perioperative doses of 15 mg dexamethasone plus a postoperative saline injection at 48 h (Group B); and three perioperative doses of dexamethasone (10 mg) (Group C). Primary outcomes were postoperative pain at rest and while walking. We also recorded consumption of analgesics and antiemetics, incidence of postoperative nausea and vomiting (PONV), C-reactive protein (CRP) and interleukin-6 (IL-6) levels, postoperative length of stay (p-LOS), range of motion (ROM), nausea, Identity-Consequence-Fatigue-Scale (ICFS), and severe complications (e.g., incidence of surgical site infection, SSI and gastrointestinal bleeding, GIB). Group B and C had significantly lower pain scores at rest than Group A on postoperative day 1. Group B and C also had significantly lower dynamic pain score, CRP, and IL-6 than Group A on postoperative day 1, 2, and 3. Patients in Group B and C had lower PONV incidence, reduced use of analgesics and antiemetics, improved ROM, shorter p-LOS, lower VAS nausea score, and lower ICFS than Group A patients. On postoperative day 3, patients in Group C had significantly lower dynamic pain and ICFS scores, IL-6, and CRP than Group B patients, as well as higher ROM. None of the groups exhibited SSI or GIB. Dexamethasone provides short-term advantages in reducing pain, PONV, inflammation, and ICFS, and increasing ROM in the early postoperative period after THA. Dexamethasone efficacy in reducing post-THA pain, inflammation, and PONV at 10 mg and 15 mg is similar during the first 48 h. Dexamethasone (30 mg) divided into three 10 mg doses was superior to two doses (15 mg) in reducing pain, inflammation, and ICFS, as well as in increasing ROM on postoperative day 3.

Effects of Intraoperative Saline-Soaked Pharyngeal Packing on Nausea, Vomiting, and Throat Pain After Nasal Surgery: A Systematic Review and Meta-Analysis

Background and Objectives: The purpose of this study was to conduct a meta-analysis of the effects of intraoperative pharyngeal packing on postoperative nausea, vomiting, and sore throat in nasal surgery patients.Methods: Databases were searched from inception to December 2022. Randomized controlled trials comparing saline-soaked pharyngeal packing (packing group) with no packing (control group) during intubation in patients undergoing nasal surgery were included. The primary outcomes of interest were the incidence of postoperative nausea, vomiting, and sore throat at 24 hours.Results: Eleven studies, including a total of 931 patients, were included. There was no significant difference between the two groups in the incidence of postoperative nausea and vomiting and severity scores at 2, 6, and 24 hours postoperatively. The incidence of throat pain was higher in the packing group than in the control group immediately after surgery and at 24 hours postoperatively. However, no significant difference was observed between the two groups in the incidence of sore throat at 6 and 12 hours postoperatively.Conclusion: Intraoperative saline-soaked pharyngeal packing did not significantly decrease postoperative nausea and vomiting. However, the use of pharyngeal packing was associated with a higher incidence of sore throat in the initial recovery period.

Efficacy of Intravenous Ibuprofen and Acetaminophen on Postoperative Pain and Tramadol Consumption in Laparoscopic Cholecystectomy: Prospective, Randomized, Double-blinded Clinical Trial

Background: Many techniques, including multimodal analgesia, have been used to manage postoperative pain after laparoscopic cholecystectomy (LC). Although the number of studies using intravenous ibuprofen (IV) is still limited, ibuprofen has been shown to have a potential role in managing postoperative pain. The primary outcome of this study is to evaluate and compare the impact of IV forms of ibuprofen and acetaminophen on 24-hour postoperative opioid consumption and pain management in patients undergoing LC. The second outcome of the study is to evaluate the impact of ibuprofen and acetaminophen on opioid-related adverse events (ORAE).
 Materials and Methods: This study was a prospective, randomized, double-blind clinical trial. Following ethical committee approval, 70 patients aged 18 to 65, American Society of Anesthesiology (ASA) score I- II, and those scheduled for LC were enrolled in the study. Patients were randomly divided into two groups. The control group (n=35) received 800 mg IV ibuprofen (group I) in 100 mL saline during surgery, while the acetaminophen group (n=35) received 1000 mg (group A). In the postoperative period, all patients received a patient-controlled analgesia (PCA) device with tramadol. The PCA device was set to a bolus dose of 10 mg and had a lockout time of 15 minutes. A blinded pain nurse assessed postoperative analgesia at 1, 2, 4, 6, 12, and 24 hours using a numerical rating scale (NRS). The incidence of postoperative nausea and vomiting (PONV), total tramadol consumption, and the need for additional analgesics during the 24-hour postoperative period were recorded.
 Results: Seventy patients who underwent LC participated in this study. The use of analgesic medications was statistically lower in group I than in the other group A. NRS scores between the IV ibuprofen and acetaminophen groups were statistically similar at 1, 2, 4, 6, 12, and 24 hours postoperatively (P>0.05). 24-hour opioid consumption was statistically significantly higher in group A than in group I (P0.05). PONV rates were similar in the ibuprofen and acetaminophen groups (P>0.05). ORAEs were similar between groups.
 Conclusion: Ibuprofen as part of tramadol-based multimodal analgesia reduced tramadol consumption compared to acetaminophen during the first 24 hours postoperatively following elective LC surgery. The IV ibuprofen-tramadol combination appeared superior to an acetaminophen-tramadol combination. ORAEs were similar in both groups.

Recovery Benefit With Total Intravenous Anesthesia in Patients Receiving Rhinoplasty.

The aim was to evaluate the difference in recovery when comparing total intravenous anesthesia (TIVA) to inhalational gas anesthesia in patients receiving rhinoplasty. Retrospective review. Postoperative anesthesia care unit (PACU). Patients who received a functional or cosmetic rhinoplasty at a single academic institution between April 2017 and November 2020 were included. Inhalational gas anesthesia was in the form of sevoflurane. Phase I recovery time, which was defined as the time it took a patient to reach ≥9/10 on the Aldrete scoring system was recorded, as well as the usage of pain medication in the PACU. The postoperative course and incidence of postoperative nausea and vomiting (PONV) were also collected. Two hundred and two patients were identified with 149 (73.76%) who received TIVA and 53 (26.24%) who received sevoflurane. For the patients who received TIVA, the average recovery time was 101.44minutes (standard deviation [SD]: 34.64) compared to an average recovery time of 121.09minutes (SD: 50.19) for patients who received sevoflurane leading to a difference of 19.65minutes (p = 0.002). Patients who received TIVA experienced less PONV (p = 0.001). There were no differences in the postoperative course including surgical or anesthesia complications, postoperative complications, hospital or Emergency Department admissions, or administration of pain medication (p > 0.05 for all). When utilizing TIVA over inhalational anesthesia, patients undergoing rhinoplasty had significantly increased benefits in terms of reduced phase I recovery times and decreased incidence of PONV. TIVA was demonstrated to be a safe and efficacious method of anesthesia for this patient population.

A comparative study of laparoscopic cholecystectomy with and without abdominal drain

Background: Laparoscopic cholecystectomy (LC) has been considered the Gold-standard for the management of benign gallbladder disease. With increasing surgeon experience and advancement of instrumentations and equipment, LC is approaching continuously toward a more safe and less invasive technique. There is a consensus that drainage should not be considered mandatory or standard after elective LC. Aims and Objectives: The aims of this study were to assess the effectiveness of the LC without abdominal drain over sub hepatic drainage and to compare the post-operative outcome between two groups. Materials and Methods: A descriptive observational comparison study has been carried out in the department of General Surgery BSMCH, from September 1, to December 1, in 130 patients undergoing elective LC. Patients have been divided into two groups: Comparison group and study group after proper matching. Data have been collected via interview, clinical examination, and scrutinizing relevant medical records. Each patient has been followed up after operation. Data have been summarized for estimating various parameters such as mean duration of surgery and hospital stay between the groups and proportion of patient complaining of pain 24 h after surgery. Results: The mean duration of surgery in drainage group is 108 min which is significantly more than the non-drainage group 88 min. In this present study, the patients with abdominal drain are showing more incidence of post-operative nausea and vomiting (PONV) 21.53% compared to no-drain group 6.15%. In this study, 35.38% of patients with subhepatic drain developed pain after surgery, whereas only 12.3% of the patients with no drain experienced the same. Overall six patients from the drain group still had significant subhepatic collection and eight patients with no drain have the same. The mean duration of stay in hospital of the drain group is 4.06 days, whereas, in no-drain group, it is 2.26. Conclusion: An uncomplicated gallstone disease can be treated by LC without need for drain with reasonable safety by an experienced surgeon. Hence, no use of drain scores over use of drain in terms of PONV, post-operative pain, and therefore, there is less use of analgesics and also short duration of hospital stay. When a dry operative field is achieved during LC the drain insertion may be avoided.

Effectiveness of Sufentanil-Based Patient-Controlled Analgesia Regimen in Children and Incidence of Adverse Events Following Major Congenital Structure Repairs.

The aim of this study was to evaluate postoperative analgesia effectiveness and patient-controlled analgesia (PCA)-related adverse events. The children who received sufentanil-based PCA following major surgery to repair congenital hip dislocation and hypospadias were divided into 3 groups: sufentanil 4 µg/kg + tramadol 10 mg/kg (ST; n = 301), sufentanil 4 µg/kg (S4; n = 211), and sufentanil 5 µg/kg (S5; n = 451). Analgesics with granisetron 0.2 mg/kg were diluted in 0.9% saline to 100 mL and infused continuously at a basal infusion rate of 1mL/h. A total of 963 children whose average age was 4 years were investigated. The incidence of moderate to severe postoperative pain during rest was significantly lower in the S5 group (0.2%) and ST group (0.3%) compared with the S4 group (3.3%) within 72 hours after surgery (P < .05), and the incidence of moderate to severe pain during activity within 72 hours was also significantly lower in the S5 group (3.5%) compared with the other 2 groups (ST, 21.9%; S4, 33.2%; P < .001). A significant difference was identified among the 3 groups in the total number of PCA administrations, but there was no statistical difference of total usage of opioids among the 3 groups. In terms of PCA-related adverse events, the incidence of postoperative nausea and vomiting in the S5 group was lower compared with the ST group within 72 hours after surgery (P < .001), and there was no significant difference compared with the S4 group (P = .254). There was also no significant difference in the incidence of pruritus and dizziness among the 3 groups. Sufentanil-based PCA can be effectively and safely used in children after major congenital structural malformation repair surgeries. The sufentanil 5 µg/kg dosage in the PCA regimen is superior to sufentanil 4 µg/kg alone or combined with tramadol in lowering moderate to severe pain.

Comparison of Performance Characteristics and Efficacy of Bilateral Thoracic Paravertebral Blocks in Obese and Non-Obese Patients Undergoing Reduction Mammaplasty Surgery: A Historical Cohort Study.

Although ultrasound (US)-guided regional anesthesia techniques are advantageous in the management of obese patients; the procedures can still be associated with technical difficulties and greater failure rates. The aim of this study is to compare the performance properties and analgesic efficacy of US-guided bilateral thoracic paravertebral blocks (TPVBs) in obese and non-obese patients. Data of 82 patients, who underwent bilateral reduction mammaplasty under general anesthesia with adjunctive TPVB analgesia between December 2016 and February 2020, were reviewed. Patients were allocated into two groups with respect to their BMI scores (Group NO: BMI<30 and Group O: BMI≥30). Demographics, ideal US visualization time, total bilateral TPVB procedure time, needle tip visualization and performance difficulties, number of needle maneuvers, surgical, anesthetic and analgesic follow-up parameters, incidence of postoperative nausea and vomiting (PONV), sleep duration, length of postanesthesia care unit (PACU) and hospital stay, and patient/surgeon satisfaction scores were investigated. Seventy-nine patients' data were complete. Ideal US visualization and total TPVB performance times were shorter, number of needle maneuvers were fewer and length of PACU stay was shorter in Group NO (p<0.05). Postoperative pain scores were generally similar within first 24 h (p>0.05). Time to postoperative pain, total analgesic requirements, incidence of PONV, sleep duration, length of hospital stay were comparable (p>0.05). Satisfaction was slightly higher in Group NO (p<0.05). US-guided TPVB performances in obese patients might be more challenging and take longer time. However, it is still successful providing good acute pain control in patients undergoing reduction mammaplasty surgeries.

The Efficacy of Transverse Abdominis Plane Block for Postoperative Analgesia in Laparoscopic Hysterectomy: A Randomized Prospective Study.

Postoperative pain is an inevitable acute pain for which a multimodal analgesic approach is required. The aim of this study was to quantify and compare the efficacy of transverse abdominis plane (TAP) block as a postoperative analgesic for patients undergoing laparoscopic hysterectomies versus intravenous opioid analgesics. Sixtyfemale patients were enrolled and randomized into two groups following a computer-generated sequence of numbers. In group T (n=30) patients received an ultrasound-guided bilateral TAP block with 20 of 0.375% levobupivacaine on each side immediately after surgery. Patients in group O (opioid group, n = 30) received intravenous (i.v.) tramadol (100mg) immediately after surgery.Rescue analgesic (inj. tramadol 50mg) i.v. bolus given in both groups if visual analog scale (VAS) >4. In the postanesthesia care unit (PACU), the vital signs, episodes of nausea, vomiting, and VAS score of each patient were recorded every two hours for the first 24 hours. Total consumption of rescue analgesic (inj. tramadol 50 mg i.v.) during the first 24 hours was significantly higher in group O (186.47+37.48mg) than in group T (107.28+26.34mg). No significant difference was observed in intraoperative vital parameters (HR, NIBP, SPO2). The VAS scores were significantly low in group T.Incidence of postoperative nausea and vomiting (PONV) was significantly higher in group O (13 out of 28 patients) than in group T (five out of 28 patients) with P value =0.043. Our study indicated bilateral ultrasound-guided TAP block is a good alternative to opioids for postoperative analgesia.

Correlation Of Age And BMI With The Incident Of Nausea And Vomiting In Patients Post Sectio Caesarian Operation With Spinal Anesthesia In Aliyah Hospital 2

Background. Postoperative nausea and vomiting are one of the complications experienced by patients with anesthesia and surgery. There are many factors that influence this occurrence, including age and BMI, where young age and obese BMI tend to experience postoperative nausea and vomiting. This is based on the fact that older age is easier to control nausea and vomiting than young people and obese BMI has more fat tissue to store anesthetic drugs so that the side effects of drugs can last longer. Method. This study used an observational analytic method with a cross sectional approach carried out at Aliyah Hospital 2. The number of samples in this study were 38 people who were taken using total sampling technique. Data collection was obtained from filling in the observation sheet and then the data was analyzed using the Fisher's Exact Test statistical test. The dependent variable in this study was postoperative nausea and vomiting and the independent variables were age and BMI. Results. The results of this study found that age did not have a significant relationship with the incidence of postoperative nausea and vomiting at Aliyah Hospital 2 (p = 0.298) and BMI had a significant relationship with the incidence of postoperative nausea and vomiting at Aliyah Hospital 2 (p = 0.019). Conclusion. From this study it can be concluded that the incidence of postoperative nausea and vomiting after spinal anesthesia is higher in patients with older age and excessive BMI.

COMPARISON OF EFFECT OF INJ DEXAMETHASONE WITH INJ ONDANSETRON AND INJ DEXAMETHASONE WITH INJ METOCLOPRAMIDE FOR PREVENTION OF POST-OPERATIVE NAUSEA AND VOMITING(PONV) AFTER GENERAL ANAESTHESIA AT TERTIARY CARE CENTER

Introduction: Postoperative nausea &amp; vomiting (PONV) are common distressing complications of anaesthesia. Pain ,nausea &amp; vomiting are frequently listed by the patient as their most important postoperative concerns. PONV results in increased patientÂ’s discomfort and dissatisfaction. Despite continuing advances in anaesthetic and surgical technique, both the incidence and severity of PONV remain relatively unchanged. Material and Methods: A total of 200 patients belonging to ASA grade 1 and 2 posted for surgery under general anaesthesia were included after satisfying the eligibility criteria. They were divided into two groups.Group O received Dexamethasone 8 mg i.v. + Ondansetron 4 mg i.v.Group M received Dexamethasone 8 mg i.v. + Metoclopramide 10 mg i.v.In this study, the primary aim was to assess the incidence of post operative nausea and vomiting in the first 8 hrs after surgery in both the groups. Results: In group M ,total 32 patients out of 100 had nausea as compared to group O where 14 patients had nausea.In group M, 19 patients had mild nausea as compared to 9 patients in group O. 13 patients had moderate nausea in group M as compared to 5 patients in group O. In group M 25 patients had episodes of vomiting out of 100 as compared to group O where 8 patients had vomiting episodes. In group M, 13 patients had mild vomiting episodes as compared to 4 patients in group O. 12 patients had moderate vomiting episodes in group M as compared to 4 patients in group O .The difference between two groups was statistically significant. Conclusion: In this study ,nausea and vomiting score was significantly low in group O which is the combination of dexamethasone and ondansetron as compared to the M group which consists of dexamethasone and metoclopramide. Thus we can conclude that dexamethasone (8 mg) and ondansetron(4 mg) combination has better antiemetic effect than the combination of dexamethasone (8 mg) and metoclopramide 10 mg) to prevent PONV after general anaesthesia.

Application of opioid-free general anesthesia for gynecological laparoscopic surgery under ERAS protocol: a non-inferiority randomized controlled trial

BackgroundEnhanced recovery after surgery (ERAS) is now widely used in various surgical fields including gynecological laparoscopic surgery, but the advantages of opioid-free anesthesia (OFA) in gynecological laparoscopic surgery under ERAS protocol are inexact.AimsThis study aims to assess the effectiveness and feasibility of OFA technique versus traditional opioid-based anesthesia (OA) technique in gynecological laparoscopic surgery under ERAS.MethodsAdult female patients aged 18 ~ 65 years old undergoing gynecological laparoscopic surgery were randomly divided into OFA group (Group OFA, n = 39) with esketamine and dexmedetomidine or OA group (Group OA, n = 38) with sufentanil and remifentanil. All patients adopted ERAS protocol. The primary outcome was the area under the curve (AUC) of Visual Analogue Scale (VAS) scores (AUCVAS) postoperatively. Secondary outcomes included intraoperative hemodynamic variables, awakening and orientation recovery times, number of postoperative rescue analgesia required, incidence of postoperative nausea and vomiting (PONV) and Pittsburgh Sleep Quality Index (PSQI) perioperatively.ResultsAUCVAS was (Group OFA, 16.72 ± 2.50) vs (Group OA, 15.99 ± 2.72) (p = 0.223). No difference was found in the number of rescue analgesia required (p = 0.352). There were no between-group differences in mean arterial pressure (MAP) and heart rate (HR) (p = 0.211 and 0.659, respectively) except MAP at time of surgical incision immediately [(Group OFA, 84.38 ± 11.08) vs. (Group OA, 79.00 ± 8.92), p = 0.022]. Times of awakening and orientation recovery in group OFA (14.54 ± 4.22 and 20.69 ± 4.92, respectively) were both longer than which in group OA (12.63 ± 3.59 and 18.45 ± 4.08, respectively) (p = 0.036 and 0.033, respectively). The incidence of PONV in group OFA (10.1%) was lower than that in group OA (28.9%) significantly (p = 0.027). The postoperative PSQI was lower than the preoperative one in group OFA (p = 0.013).ConclusionIn gynecological laparoscopic surgery under ERAS protocol, OFA technique is non-inferior to OA technique in analgesic effect and intraoperative anesthesia stability. Although awakening and orientation recovery times were prolonged compared to OA, OFA had lower incidence of PONV and improved postoperative sleep quality.Trial registrationChiCTR2100052761, 05/11/2021.

A randomized controlled trial evaluating the effects of transversus abdominis plane block with compound lidocaine hydrochloride injection on postoperative pain and opioid consumption and gastrointestinal motility in patients undergoing gynecological laparotomy.

Incorporation of transversus abdominis plane (TAP) block into multimodal analgesia has been emphasized in Enhanced Recovery protocols (ERPs). However, benefit is limited in clinical practice. A potential explanation is the short duration of analgesia of standard local anesthetics. Herein, this randomized, double-blind, controlled trial evaluated whether TAPB with long-acting compound lidocaine hydrochloride injection reduces postoperative pain. 164 patients undergoing elective gynecological laparotomy under sevoflurane anesthesia randomly received ultrasound-guided TAP block with either saline, or ropivacaine, or compound lidocaine before anesthesia induction. The postoperative pain intensity (primary outcome) was evaluated by pain 11-point numerical rating scale. We also recorded sufentanil consumptions, time to first flatus, side-effects and hospital stay after surgery. We reported that pain scores at rest at postoperative 3h in group 0.375% ropivacaine was lower than that in group saline [mean 2.4 (SD 1.2) vs. 3.0 (1.0), p = 0.036]. Compared with saline, 0.4% and 0.6% compound lidocaine caused lower pain scores at rest at postoperative 12h [2.8 (0.9) vs. 2.1 (0.9) and 2.0 (0.9), p = 0.016 and p = 0.006]. Sufentanil usage for the first postoperative 48h was lower in group 0.6% compound lidocaine than group saline [24.2 (5.4) vs. 45.6 (7.5) µg, p < 0.001]. Time to first flatus and hospital stay after surgery was shortest and the incidence of postoperative nausea was lowest in patients receiving 0.6% compound lidocaine. TAP block with 0.6% compound lidocaine hydrochloride injection attenuates postoperative pain, reduces opioid consumption, accelerates gastrointestinal function recovery, and shortens length of hospital stay in patients after gynecological laparotomy.

Effect of thumb-tack needle on gastrointestinal function recovery after cesarean section under the concept of enhanced recovery after surgery

To observe the synergistic effect and safety of combined use of houpo paiqi mixture and thumb-tack needle on promoting gastrointestinal function recovery after cesarean section. Parturients receiving cesarean section were randomly divided into the control group (29 cases), the traditional Chinese medicine (TCM) group (30 cases) and needle+TCM group (30 cases). The control group received only routine postoperative treatment. Besides the treatment as the control group, parturients in the TCM group were given 50 mL houpo paiqi mixture 6 h and 10 h after cesarean section respectively. Besides the treatment as the TCM group, parturients in the needle+TCM group received thumb-tack needle treatment at bilateral Zusanli(ST36), Tianshu(ST25), Shangjuxu(ST37) and Sanyinjiao(SP6), Zhongwan(CV12), Qihai(CV6), with auricular pressure at bilateral otopoints Zigong(Uterus), Wei(Stomach) and Dachang(Large intestine), within 1 h after the parturients returned to the ward after the operation. Each acupoint was pressed for 10 s and performed acupressure every 4 h (except sleeping hours), continuously for 3 d. The time of bowel sound recovery, the time to the first postoperative exhaust and defecation, the time of postoperative semi-fluid diet recovery, incidence of postoperative nausea and vomiting (PONV) and abdominal distention, and abdominal pain VAS score were recorded and analyzed. The safety of the treatments was also evaluated. Compared with the control group, the time of bowel sounds recovery, the time to the first postoperative exhaust and the time of postoperative semi-fluid diet recovery were significantly shortened in the TCM and needle+TCM groups (P<0.01); the time to the first postoperative defecation were significantly shortened (P<0.01), incidence of both abdominal distention and PONV were significantly decreased in the needle+TCM group (P<0.05, P<0.01); incidence of abdominal distention were significantly decreased in TCM group (P<0.05). Compared with the TCM group, the time of bowel sounds recovery, the time to the first postoperative exhaust and defecation, and the time of postoperative semi-fluid diet recovery were significantly shortened (P<0.01), and incidence of both abdominal distention and PONV were significantly decreased in the needle+TCM group (P<0.05). VAS scores of the three groups decreased gradually over time (P<0.01). Compared with the control and TCM groups, VAS scores of the needle+TCM group significantly decreased at 24 h, 48 h and 72 h after operation (P<0.01). No treatment-related adverse reactions were observed during the whole trial. On the base of the treatment with houpo paiqi mixture, the addition of thumb-tack needle treatment exerted positive synergistic effect on gastrointestinal function recovery after cesarean section, with high safety, which is worthy of clinical application.

The Clinical Application of Ultra-Fast-Track Cardiac Anesthesia in Right-Thoracoscopic Minimally Invasive Cardiac Surgery: A Retrospective Observational Study

The purpose of this study was to investigate the effect of ultra-fast-track cardiac anesthesia (UFTCA) on rapid postoperative recovery in patients undergoing right-thoracoscopic minimally invasive cardiac surgery. A retrospective observational study. A single large teaching hospital. A total of 153 patients who underwent right-thoracoscopic minimally invasive cardiac surgery between January 2021 and August 2021 were enrolled. The inclusion criteria were American Society of Anesthesiologists grade I to III, New York Heart Association (NYHA) cardiac function class I to III, and age ≥18 years. The exclusion criteria were NYHA class IV, local anesthetic allergy, severe pulmonary hypertension (pulmonary arterial systolic pressure, PASP >70 mmHg), age ≤18 years or ≥80 years old, emergency surgery, and patients with incomplete or missing data. Finally, a total of 122 patients were included and grouped by different anesthesia strategies. Sixty patients received serratus anterior plane block-assisted ultra-fast- track cardiac anesthesia (UFTCA group), and 62 patients received conventional general anesthesia (CGA group). The primary outcomes were lengths of hospital stay and postoperative intensive care unit (ICU) stay. The secondary outcomes were postoperative pain scores, opioids use, postoperative chest tube drainage, and complications. The intraoperative dosages of sufentanil and remifentanil in the UFTCA group were significantly lower than those in the CGA group (66.25 ± 1.03 µg v 283.31 ± 11.36 µg, p < 0.001; and 1.94 ± 0.38 mg v 2.14 ± 0.99 mg, p < 0.001, respectively). The incidence of postoperative rescue analgesia in the UFTCA group was significantly lower than that in the CGA group (10 patients [16.67%] v 30 patients [48.38%], p < 0.001). In the postoperative ICU, there were fewer patients with pain score Numeric Rating Scale ≥3 in the UFTCA group than that in the CGA group (10 patients [16.67%] v 29 patients [46.78%], p < 0.001). The postoperative extubation time in the UFTCA group was shorter than that in the CGA group (0.3 hours [range, 0.25-0.4 hours] v 13.84 hours [range, 10.25-18.36 hours], p < 0.001). Lengths of ICU stay and hospital stay in the UFTCA group were shorter than those in the CGA group (27.73 ± 16.54 hours v 61.69 ± 32.48 hours, p < 0.001; and 8 days [range, 7-9] v 9 days [range, 8-12], p < 0.001, respectively). Compared with the CGA group, the patients in the UFTCA group had less chest tube drainage within 24 hours after surgery (197.67 ± 13.05 mL v 318.23 ± 160.10 mL, p < 0.001). There were no significant differences in in-hospital mortality, postoperative bleeding, or secondary surgery between the 2 groups. The incidences of postoperative nausea, vomiting, or atelectasis were comparable between the 2 groups. Serratus anterior plane block-assisted ultra-fast-track cardiac anesthesia can promote rapid postoperative recovery in patients with right-thoracoscopic minimally invasive cardiac surgery. This anesthesia regimen is clinically safe and feasible.

Analgesic effect of erector spinae plane block in adults undergoing laparoscopic cholecystectomy: a systematic review and meta-analysis of randomized controlled trials

BackgroundLaparoscopic cholecystectomy is the gold standard surgical procedure for treating gallstone disease. Despite it being minimally invasive, various medications and methods are used to alleviate postoperative pain, and some patients still experience moderate-to-severe pain. This is a crucial problem that must be solved to avoid chronic pain. As part of postoperative multimodal analgesia, regional block is being increasingly applied in surgery under ultrasound guidance. We aimed to evaluate the analgesic effect of erector spinae plane block in adult patients undergoing laparoscopic cholecystectomy.MethodsPubMed, Cochrane Library, EMBASE, and Web of Science were searched for randomized controlled trials investigating the efficacy of erector spinae plane block on postoperative pain after laparoscopic cholecystectomy. The primary outcome was the postoperative pain score. The secondary outcomes were the cumulative intraoperative and postoperative opioid consumption at 24 h, incidence of postoperative nausea and vomiting, and shoulder pain after surgery. The results were pooled using the fixed- or random-effects model with Review Manager 5.3.ResultsFifteen randomized controlled trials involving 947 patients were included in the analysis. Postoperative pain score in the erector spinae plane block group was lower than that in the control group at postoperative 12 h (MD − 0.81, 95% CI − 1.1 to − 0.51, p < 0.00001) and 24 h (MD − 0.41, 95% CI − 0.62 to − 0.19, p = 0.0002). Cumulative opioid consumption was lower in the erector spinae plane block group than in the control group at postoperative 24 h (MD − 7.88, 95% CI − 10.17 to − 5.58, p < 0.00001). The erector spinae plane block group also experienced a lower incidence of postoperative nausea and vomiting than the control group. Opioid consumption and the incidence of postoperative nausea and vomiting were similar between the erector spinae plane block group and other block groups, including the oblique subcostal transversus abdominis plane block and quadratus lumborum block groups.ConclusionsUltrasound-guided erector spinae plane block provides effective postoperative analgesia in adults undergoing laparoscopic cholecystectomy.

Remimazolam as a Potential Alternative to Propofol for General Anesthesia: A Meta-Analysis of Randomized Controlled Trials

Objective: This meta-analysis aimed to systematically review randomized controlled trials (RCTs) to evaluate whether remimazolam can be an alternative to propofol for general anesthesia.Materials and Methods: We conducted a comprehensive search of databases, including PubMed, Web of Science, Embase, Google Scholar, and Cochrane Library, using the population, intervention, comparison, outcome, study design (PICOS) method from inception to December 31, 2022, without language limitations. RCTs comparing the adverse effects, anesthetic efficacy, and quality of recovery between remimazolam and propofol in patients undergoing general anesthesia were included.Results: Eleven studies involving a total of 1255 patients were included in the meta-analysis. Pooled pooled results demonstrated that total adverse events in the remimazolam group had lower total adverse events compared to the propofol group [odds ratio [OR] = 0.12, 95% confidence interval [CI] (0.06, 0.26), I2 = 20%, p < 0.00001]. The propofol group showed higher rates of hypotension (OR 0.32, 95% CI [0.22, 0.45], I2 = 0%, p < 0.00001), injection pain (OR 0.02, 95% CI [0.01, 0.06], I2 = 33%, p < 0.00001), hypoxemia (OR 0.08, 95% CI [0.03, 0.21], I2 = 0%, p < 0.00001), and dizziness (OR 0.18, 95% CI [0.06, 0.57], I2 =19%, p = 0.004]) when compared to the remimazolam group, indicating significant differences. No significant difference was found between the two groups regarding the incidence of postoperative nausea and vomiting, somnolence, and agitation was found between the two groups.Conclusion: Remimazolam demonstrated non-inferiority to propofol in terms of its capacity as an intravenous agent for general anesthesia. It has the potential to serve as an alternative to propofol.

Opioid-based Anaesthesia versus Opioid Free Anaesthesia in Laparoscopic Cholecystectomies: A Randomised Clinical Study

Introduction: Intravenous opioids have been frequently used to provide analgesia and supplemental sedation during general anaesthesia or monitored anaesthesia care. Opioid Free Anaesthesia (OFA) is a multimodal approach which combines different drugs likes lignocaine, dexamethasone, paracetamol and dexmedetomidine with different techniquessuch as hypnosis, sedation, analgesia and sympatholysis. Thus, reducing and avoiding opioids perioperatively will lead to decrease in opioid related adverse effects with better postoperative outcomes. Aim: To compare OFA and Opioid-based Anaesthesia (OBA) in terms of haemodynamic stability, speed and quality of recovery, postoperative pain score and analgesic requirement. Material and Methods: The present study was a randomised study conducted over a period from June 2021 to September 2022, in which 90 patients of American Society of Anaesthesiologists (ASA) Grade I,II, 20-60 years of age undergoing elective Laparoscopic Cholecystectomy (LC) were divided into OBA fentanyl and OFA-lignocaine and dexmedetomidine. A standard general anaesthesia protocol of the institute was followed. OBA group received fentanyl (2 μg/kg) over 10 minutes before induction of anaesthesia and OFA group received lignocaine (2 mg/kg) and dexmedetomidine (0.5 μg/kg) both intravenously over 10 minutes before induction of anaesthesia. In OFA group analgesia was maintained by infusion of lignocaine 2 mg/kg/hr and dexmedetomidine 0.5 μg/kg/hr whereas in OBA group fentanyl 0.5 μg/kg was given whenever required till the gallbladder was resected. Postoperative intraperitoneal instillation of gallbaldder fossa was done with 20 mL 0.5% bupivacaine. Intraoperative mean Heart Rate (HR) and Mean Arterial Pressure (MAP) were recorded. Postoperative speed and quality of recovery, pain score, analgesic requirements and incidence of Postoperative Nausea and Vomiting (PONV) were noted. Paracetamol 15 mg/kg was given intravenously whenever Numerical Rating Scale (NRS) score was ≥6. Comparison of means between the two groups was done using unpaired t-test, association between two non parametric variables was done using Pearson Chi-square (χ2 test) test. Results: The mean age, sex, weight, ASA and duration of surgery were comparable in both the groups. The mean HR and mean MAP were significantly lower in OFA group compared to the OBA group at all the time points (p-value=0.001). Although postoperative speed of recovery was slower in OFA group, the overall quality of recovery was better (p-value=0.001). The postoperative pain score, analgesic requirement and incidence of nausea and vomiting were all significantly less in OFA group as compared to OBA group with p-values of 0.02, 0.001 and 0.02, respectively. Conclusion: OFA is new anaesthetic approach that provides better perioperative haemodynamic stability, postoperative pain control with less PONV and thus can be used safely and successfully

Comparison of General Anaesthesia and Epidural Anaesthesia in Lumbar Microdiscectomies- A Prospective Comparative Study

Introduction: Lumbar Microdiscectomy (LMD) is most commonly performed under General Anaesthesia (GA). Regional techniques are being used more widely now, with Epidural Anaesthesia (EA) being safer than Spinal Anaesthesia (SA). Regional anaesthetic methods are being used increasingly, with EA being less harmful than spinal with respect to cardiac and neurological complications. Aim: To compare the intraoperative and postoperative outcomes of GA and EA in single level lumbar microdiscectomies. Materials and Methods: This prospective comparative study was conducted at a single tertiary care centre between April 2014 to April 2018 and Study was conducted among 40 patients who were posted for single level lumbar microdiscectomies. The patients underwent surgery under group GA and group EA. Intraoperatively, parameters like Heart Rate (HR), Mean Arterial Pressure (MAP), Surgical Onset Time (SOT), Surgical Time (ST), Total Operating room Time (TOT) and postoperatively Visual Analog Scale (VAS) for pain, the Total Analgesic Dose (TAD) of fentanyl, Postoperative Nausea and Vomiting (PONV) and the level of satisfaction with regard to pain relief (4-point Likert scale) for the first 24 hours were compared. The data were analysed using Statistical Package for Social Sciences (SPSS) version 18 software. Mean, percentage, student’s t-test, χ2 test, Mann-whitney test and appropriate statistical tests were used. Results: A total of 40 patients were enrolled in the present study with rather similar demographic characteristics in both groups. The SOT was significantly more in the EA group (24.30±2.958 min) when compared to the GA group (14.05±2.259) minutes. However, the ST and TOT did not show much of a difference. Intraoperatively, group GA showed significantly high HR and MAP values when compared to group EA (p&lt;0.001). Postoperatively, VAS for pain and the TAD of fentanyl were found to be significantly lesser in the EA group, when compared to GA group. The incidence of Postoperative Nausea and Vomiting (PONV) was less in EA group. The level of satisfaction with regard to pain relief at the end of first 24 hours was more among patients in EA group. Conclusion: The present study concludes that, EA may be used as an alternative to GA in single level lumbar microdiscectomies.
