Efficacy and Complications Comparison Between Emergent and Elective Laparoscopic Cholecystectomy Surgery

Background: Laparoscopic cholecystectomy (LC) is the preferred surgical procedure for treating symptomatic gallstone (GS) disease. Objectives: This study aimed to evaluate and compare the outcomes of emergent and elective LC, focusing on complications, conversion rates, duration of surgery (DOS), length of hospital stay, and post-operative pain. Methods: A total of 166 patients who underwent LC surgery at Baqiyatallah Hospital, Tehran, Iran, between 2021 and 2022 were included in the study. Of these, 64 patients underwent emergent LC, and 102 underwent elective LC. The groups were compared for complications, conversion rates, DOS, length of hospital stay, and post-operative pain. Results: The study revealed that while intraoperative complications did not differ significantly between the two groups (P = 0.14), there was a significant difference in the conversion of surgical methods from three to four trocars (P = 0.007). Additionally, more patients in the emergent group required drain insertion during surgery (P = 0.003). Regarding post-operative outcomes, no significant differences were observed between the emergent and elective LC groups in terms of local (P = 0.77) and systemic complications (P = 0.37). However, patients in the elective LC group experienced a significantly shorter post-operative hospital stay (P = 0.002). Pain levels one day (1.02 ± 0.80) and one week (0.14 ± 0.43) after surgery were lower in the elective LC group. Furthermore, patients in the elective group returned to daily activities earlier (3.77 ± 1.21 days). Conclusions: The findings of this study indicate that emergent LC is as safe as elective LC. However, patients undergoing elective LC may benefit from a shorter recovery period and reduced post-operative pain. Overall, LC remains a low-risk and safe option for managing emergent gallstone cases.

Effect of ultrasound-guided individualized positive end-expiratory pressure on the severity of postoperative atelectasis in elderly patients: a randomized controlled study

Postoperative pulmonary complications (PPCs) are common in patients undergoing general anesthesia, with atelectasis being a key contributor that increases postoperative mortality and prolongs hospitalization. Our research hypothesis is that ultrasound-guided individualized PEEP titration can reduce postoperative atelectasis. This single-center randomized controlled trial recruited elderly patients for laparoscopic surgery. Patients were randomly assigned to two group: the study group (individualized PEEP groups, PEEP Ind group) and the control group (Fixed PEEP group, PEEP 5 group). All patients in these two groups received volume-controlled ventilation during general anesthesia. Patients in the study group were given ultrasound-guided PEEP, while those in the control group were given a fixed 5 cmH2O PEEP. Bedside ultrasound assessed lung ventilation. The primary outcome was the severity of atelectasis within seven days post-surgery. Eighty-nine patients scheduled for elective laparoscopic radical surgery for colorectal cancer were enrolled in our study. Lung ultrasound scores (LUSs) in the study group during postoperative seven days was significantly decreased compared with that in the control group (P < 0.05). The severity of postoperative atelectasis in the study group was significantly improved. The incidence of PPCs during postoperative 7 days in the study group was significantly less than that in the control group (48.6% vs. 77.8%; RR = 0.625; CI = 0.430–0.909; P = 0.01). In elderly patients undergoing laparoscopic radical resection, lung ultrasound-guided individualized PEEP can alleviate the severity of postoperative atelectasis.Clinical trial number and registry URL: No. ChiCTR2200062979 (https://www.chictr.org.cn).

BN SO04 - The value of routine histopathology analysis of gallbladder specimens after elective and emergency laparoscopic cholecystectomy

Abstract Background Gallbladder cancer is not among the 20 most common cancers in the UK, accounting for less than 1% of all new cancer cases with a peak rate at 85-89 years of age. There is a dominant routine conception among surgeons to send the gallbladder specimen for histopathology even if there is no gross features that raise suspicion for neoplasm. In this study, we are trying to get evidence of the value of routine histopathology analysis of gallbladder specimens after elective and emergency laparoscopic cholecystectomy surgeries in Warwick hospital. Method The record of all the patients who underwent laparoscopic cholecystectomy ( elective, expiated and emergency ) in Warwick hospital in the period between 01/07/2023 – 30/01/2024 ( 7 months) were collected, reviewed and underwent data analysis Results A total of 171 specimens were sent for histo-pathology analysis. Only one patient had low grade dysplasia with no malignant features. No routine follow-up decided for him/her after upper GIT MDT discussion. The incidence rate was 0% of neoplasm and 0.6% of low-grade dysplasia. Conclusion No specimen in the study had suspicious gross features of malignancy. Using a selective system is more logical and economic than the routine sending for histopathology after elective and emergency laparoscopic cholecystectomy if there are no suspicious features in the specimen.

Comparison of surgical performance using articulated (ArtiSential®) and conventional instruments for colorectal laparoscopic surgery: A single-centre, open, before-and-after, prospective study.

Rigid surgical instruments limit movement whereas articulated instruments offer better control in small spaces and allow for intuitive and ergonomic movements. However, the effectiveness of the use of articulated instruments in improving colorectal laparoscopic outcomes remains unclear. The aim of this work was to determine whether colorectal laparoscopic surgical proficiency improved when multijoint instruments were used instead of conventional ones. We enrolled 70 consecutive patients (n = 20 for conventional instruments) aged 19-80 years who underwent elective laparoscopic surgery for colorectal diseases. Unedited surgery videos were validated using the modified Global Operative Assessment of Laparoscopic Skills (mGOALS) scale. Learning curves were analysed using a cumulative sum control chart for mGOALS grades. The surgery type, length of hospital stay and 30-day postoperative complication rates were comparable between the groups, and the surgeon's mGOALS grades were similar (p = 0.190). However, in the articulated group, the scores were significantly higher for depth perception (p = 0.012) and tissue-handling domains (p = 0.046), while surgical duration was significantly shorter and intraoperative blood loss was significantly lower (p = 0.022), compared with those in the conventional (p = 0.002) group. Learning curve findings indicated that the first 10 and subsequent 40 surgeries in the articulated group were within the inexperienced and experienced phases, respectively. The mGOALS score in the experienced phase improved in the articulated group compared with that in the conventional group (p = 0.036). The use of articulated instruments in laparoscopic colorectal surgery showed potential benefits. Further studies are needed to confirm these findings.

Variants for dosing of rocuronium taken into obesity during general anesthesia in gynecological laparoscopic surgery

The objective was to identify the optimal method of dosing the muscle relaxant rocuronium during gynecological laparoscopic surgery in obese patients.Materials and methods. The study included 36 women with obesity II–III degree, which performed elective gynecological laparoscopic surgery. They were divided into 3 groups. In group 1, rocuronium were dosed at the rate of 0.6 mg/kg of ideal body weight calculated by the Lorentz formula. In group 2, rocuronium were dosed at the rate of 0.6 mg/kg of actual body weight. In group 3, rocuronium were dosed at the rate of 22.5 mg/m2 of body surface area. The comparison group (group 0) included 20 patients with body mass index equal to 18.5–25 kg/m2.Results. The shortest time for the onset of deep neuromuscular block was noted in groups 2 and 3, and the longest, comparable to the indicator in group 0, was in group 1 (p &lt; 0.05). The time from rocuronium administration to the onset of restoration of neuromuscular conduction was the shortest in group 1: 22 [20; 25] minutes, and the longest in group 2: 40 [35; 45] min. There was no statistically significant difference in the dosing of rocuronium in obese patients at body surface area in group 3 compared with dosing for actual weight in group 0: 27 [22; 29] and 27 [25; 33] min, respectively. The recovery time of neuromuscular conduction from TOF = 1 to TOF = 25% was the shortest in group 1 (23 [18; 24] min) and was significantly different from the value in groups 2 and 3, as well as in patients of group 0. In groups 0, 2, 3, values of this indicator were identical. The recovery index did not differ significantly in all four groups.Conclusion. Dosing rocuronium in obese patients based on body surface area has an advantage for comparison over dosing based on both actual and ideal body weight, resulting in greater predictability of neuromuscular block dynamics.

Postoperative quality of recovery comparison between ciprofol and propofol in total intravenous anesthesia for elderly patients undergoing laparoscopic major abdominal surgery: A randomized, controlled, double-blind, non-inferiority trial

Study objectivesWe conducted a non-inferiority study to assess the postoperative quality of recovery (QoR) in elderly patients receiving ciprofol or propofol total intravenous anesthersia(TIVA)after elective laparoscopic major abdominal surgery, with QoR-15 scores as the main measure. DesignA prospective, double-blind, randomized non-inferiority trial was conducted in the theater, post-anesthesia care unit (PACU), and the ward. Participants144 elderly patients (age ≥ 65 years) were randomly assigned to either the ciprofol group or the propofol group. InterventionsThe ciprofol group received continuous infusion of ciprofol with remifentanil, and the propofol group received infusion of propofol with remifentanil. Outcome measuresThe primary outcome was the QoR-15 on the first postoperative day (POD1), assessed in both intention-to-treat and per-protocol populations, with the mean difference between groups compared to a non-inferiority threshold of −8. Additional assessments included QoR-15 scores on POD2, 3, and 5 for both analysis sets. Other evaluated perioperative value factors included hemodynamic parameters and injection discomfort in the intention-to-treat analysis. A linear mixed model was utilized to examine the impact of group-time interactions on hemodynamic data and QoR-15. Main resultsThe QoR-15 scores on POD1 in the ciprofol group were non-inferior to those in the propofol group both in intention-to-treat set (mean [95 %CI], 95.9[93.7–98.2] vs. 95.6 [93.3–97.8]; mean difference [95 % CI], 0.4 [−2.8–3.5]; P<0.001 for noninferiority) and per-protocol set (mean [95 %CI], 96.7 [94.4–99.0] vs. 95.7 [93.4–98.0]; mean difference [95 % CI], 1.0 [−2.2–4.3]; P<0.001 for noninferiority). Comparable outcomes were noted on postoperative days 2, 3, and 5 following the procedure in both analysis sets. Additionally: compared with propofol group, the occurrence of injection pain was lower (2.8 % vs. 27.8 %, P < 0.001); the hypotension was less frequent (33.3 % vs. 54.2 %, P = 0.012); the bradycardia was more common (38.9 % vs. 23.6 %, P = 0.048). ConclusionsCiprofol is not inferior to propofol in QoR. Ciprofol can be suitably administered to elderly patients undergoing elective laparoscopic major abdominal surgery.

Ultrasound Guided Erector Spinae Plane Block versus Oblique Subcostal Transversus Abdominis Plane Block for Postoperative Analgesia in Adults Patients after Laparoscopic Colorectal Surgery

Abstract Background Major abdominal surgery can cause significant post-operative pain and stress. Thoracic epidural analgesia (TEA) remains the gold- standard in its management. However, it is not without side effects or potential risks. Regional techniques might offer an alternative when thoracic epidural analgesia (TEA) is not possible. Aim of the Work The aim of this study is to test the efficacy of ultrasound guided erector spinae plane block versus ultrasound guided oblique subcostal TAP block as regards its efficacy, hemodynamic stability, onset of post-operative pain, amount of post-operative narcotics used. Patients and Methods In the current study, forty patients scheduled for elective laparoscopic colorectal surgery received general anaesthesia were included. Patients were divided randomly into two groups, each group includes 20 patients. Group T: Patients in this group received ultrasound guided OSTAP block after induction of general anaesthesia. Group E: Patients in this group received ultrasound guided ESP block after induction of general anaesthesia. Results As regard the analgesic parameters recorded in the current study; the NRS was significantly lower in Group E (ESP) block when compared with that of Group T (OSTAP) block and showed significant difference between both groups at 4, 6, 8 and 10 hrs postoperatively. Time to rescue analgesia, there was clinically and statistically highly significant longer time to ist rescue analgesic in group E (ESP) block was 15.68+1.50 hours compared to that of group T (OSTAP) block was 9.56+2.41 hours. These findings were in an array with a case series done by Luis-Navarro and his colleagues who reported that the first rescue analgesic was required only at 16 hours after ESP block. In the current study, total meperidine consumption with the mean total consumption in each group was 75+0.37 mg in the ESP block group compared with 125+0.87 mg in the OSTAP block group there was highly statistically significant higher mean of total analgesic consumption in group T compared to group E. Conclusion Erector spinae plane block under ultrasound guidance for laparoscopic colorectal surgery provides a longer duration and better quality of postoperative analgesia, as well as reducing the postoperative analgesic consumption when compared to oblique subcostal transversus abdominis plane block for laparoscopic colorectal surgery. Both blocks are mostly devoid of complications, and they provide reliable and effective postoperative analgesia in patients undergoing laparoscopic colorectal surgery.

Low pneumoperitoneum pressure on venous thromboembolism in laparoscopic colorectal cancer surgery: A randomized controlled study

IntroductionVenous thromboembolism (VTE) poses a significant risk in colorectal cancer surgeries due to hypercoagulability and the anatomical challenges of the pelvic cavity. With the advancement of minimally invasive techniques, intraoperative strategies for preventing VTE may prove to be effective. This study explores the effects of intraoperative pneumoperitoneum pressures on VTE incidence following colorectal cancer surgeries. MethodsThis single center parallel randomized controlled double-blind, trial involved 302 patients undergoing elective laparoscopic or robotic colorectal surgery. Patients were randomized to either a standard pneumoperitoneum pressure group (SP: 15 mmHg) or a low-pressure group (LP: 10 mmHg). Primary outcomes measured were the incidence of VTE, including symptomatic and asymptomatic DVT and PE. Secondary outcomes included postoperative D-dimer levels, surgery duration, blood loss, surgeon satisfaction, and oncological quality. ResultsOut of 302 randomized patients, 275 were evaluable post exclusions, with 138 in the SP group and 137 in the LP group. The incidence of VTE was 10.9 % in the SP and 13.9 % in the LP group, with no significant difference between the two (P = 0.450). Secondary outcomes such as D-dimer levels, surgery duration, and blood loss showed no significant differences between two groups. Surgeon satisfaction and oncological outcomes were similarly comparable. ConclusionsThe trial demonstrated no significant difference in the incidence of VTE between standard and low pneumoperitoneum pressures. This suggests that lower pressures may not necessarily provide a benefit in reducing postoperative VTE in colorectal cancer surgeries.

Nomogram-based prediction of emergence delirium in elderly patients undergoing laparoscopic surgery

BackgroundA nomogram model has been developed to forecast the incidence of emergence delirium (ED) in elderly patients undergoing laparoscopic surgery. MethodsA secondary analysis was performed on the eMODIPOD trial, which involved elective laparoscopic surgery patients at Xiangya Hospital between October 2017 and October 2019. To assess ED, the Richmond Agitation Sedation Scale (RASS) was combined with the Intensive Care Unit (CAM-ICU) scale, and patients were categorized as ED or non-ED based on the results. The two groups were compared in terms of perioperative information and test results. Logistic regression was utilized to investigate factors contributing to ED occurrence in elderly patients following laparoscopic surgery, and a nomogram was constructed to depict this. The diagnostic performance was evaluated through the utilization of the area under the receiver operating characteristic curve (AUROC) and a calibration plot. Simultaneously, to appraise the clinical value, decision curve analysis (DCA) was employed to assess the clinical value. ResultsOf the 565 patients subject to laparoscopic surgery, 94 were subsequently diagnosed with emergence delirium (ED), yielding a positive rate of 16.6 %. The developed Nomogram model was an amalgamation of several variables, which included preoperative cognitive function, educational level, dezocine, penehyclidine, ASA grading, blood loss, fluid infusion, and Post Anesthesia Care Unit-numerical rating scale (PACU-NRS). The model’s performance was commendable in terms of its discrimination power, as signified by an area under the curve of 0.713(95 % CI = 0.655–0.772). Furthermore, it exhibited adequate calibration, as affirmed by the Hosmer-Lemeshow test (χ2 = 2.243, p = 0.326). Internal validation of the model further emphasized its superior discrimination and calibration capabilities. The decision curve analysis pointed out that when the threshold probability exceeded 0.1, the Nomogram model delivered more substantial benefits compared to the treat-all and treat-none approaches. ConclusionsThis scoring system represents the pioneering Nomogram model utilized for predicting emergence delirium (ED) in geriatric patients undergoing laparoscopic surgery. It exhibits robust efficacy in forecasting the risk of ED, thereby furnishing valuable insights for the prevention, management, and treatment of ED.

Effects of opioid-sparing general anesthesia on postoperative nausea and vomiting in laparoscopic gynecological surgery.

In this study, we aimed to investigate whether opioid-sparing anesthesia (OSA) reduces postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic gynecological surgery. Adult patients undergoing elective laparoscopic gynecological surgery were randomly assigned to either the opioid-using anesthesia (OUA) or the OSA groups. In the OUA group, remifentanil was administered as an opioid during general anesthesia. In the OSA group, apart from a single dose of 5 μg/kg of alfentanil for tracheal intubation, no other opioids were used. In both groups, a multimodal intravenous non-opioid analgesic regimen was used preferentially in the post-anesthesia care unit (PACU). The primary outcome was the incidence of PONV, assessed by symptoms until the postoperative day (POD) 1. A total of 120 patients were included in this study. The incidence of nausea in the PACU was significantly lower in the OSA group compared to in the OUA group (31.7% in the OSA group vs. 51.7% in the OUA group, P = 0.026). Pain scores and the incidence of opioid analgesic administration were lower in the OSA group during PACU stay, resulting in a significantly lower number of patients requiring rescue opioid analgesics (3.3% vs. 18.3%, P = 0.008). There were no significant differences in intraoperative vital signs, hemodynamic interventions, or duration of PACU and hospital stay between the two groups. OSA significantly reduced postoperative nausea, pain scores, and the need for rescue analgesics in the PACU without increasing hemodynamic instability in patients undergoing laparoscopic gynecological surgery.

Addition of nitrous oxide and oxygen to carbon dioxide pneumoperitoneum during laparoscopic surgery for pain reduction: A double-blinded randomized controlled trial.

To examine if peritoneal conditioning with an altered insufflation gas mixture is associated with reduced postoperative pain intensity compared to the standard insufflation gas (i.e., 100% CO2). A prospective, single-centre, randomized, double-blind, superiority trial was performed. This study was conducted between 4 April 2019 and 10 February 2022 at the Jessa Hospital, Hasselt, Belgium. Patients scheduled for elective gynaecologic laparoscopic surgery. Seventy-four patients scheduled for elective gynaecologic laparoscopic surgery were randomised to receive either the standard insufflation gas with 100 CO2 (n = 37; control group) or the altered gas mixture of 86% CO2, 10% N2O and 4% O2 (n = 37; experimental group). Postoperative pain was assessed at 4, 8 and 24 hours after surgery and on postoperative day (POD) 7 by an 11-point Numeric Rating Scale, with 0 indicating no pain and 10 indicating worst imaginable pain. No significant differences were found between the control and experimental groups regarding postoperative pain at 4, 8 and 24 h after surgery, as well as on POD7. In addition, the median (25% and 75%) total amount of IV piritramide consumption during the first 24 h after surgery was not significantly different between groups (control group: 18.0 [10.0, 27.0] mg vs. experimental group: 17.0 [10.0, 34.0] mg, p = 0.62). The alternative insufflation gas mixture comprising 86% CO2, 10% N2O and 4% O2 used for the pneumoperitoneum during gynaecologic laparoscopic surgery does not appear to reduce postoperative pain compared to the standard insufflation gas of 100% CO2.

CHRM3 (rs2165870) gene polymorphism is related to postoperative vomiting in female patients undergoing laparoscopic surgery. Prospective observational study.

Postoperative nausea and vomiting are common complications after surgery, and female patients are more likely to experience these adverse events. The goal of this study was to explore the relationship between the CHRM3 rs2165870 polymorphism and postoperative vomiting incidence in female patients who underwent laparoscopic surgery. Two hundred female patients who underwent elective laparoscopic surgery with subsequent patient-controlled intravenous analgesia using dexmedetomidine and sufentanil were prospectively enrolled. The CHRM3 rs2165870 and KCNB2 rs349358 polymorphisms were genotyped using MassARRAY SNP typing technology. Demographic data and preoperative laboratory results of all patients were recorded. Postoperative analgesia-related information, incidence of postoperative nausea and vomiting, and other adverse events were followed up and recorded for analysis. No significant differences were observed in any of the demographic characteristics of these patients among the different genotype carriers (P>0.05). The percentages of patients with each genotype of CHRM3 were 67% (GG), 28.5% (GA) and 4.5% (AA). We found that the AA or A allele of the CHRM3 rs2165870 polymorphism elevated the risk of postoperative vomiting (AA versus GG; OR, 6.94; 95% CI, 1.49-32.46; P = 0.014; A versus G; OR, 2.52; 95% CI, 1.22-5.19; P = 0.012). The percentages of patients with each genotype of KCNB2 were 84.5% (TT), 15.5% (CT) and 0% (CC). There were no significant differences in the postoperative nausea or vomiting rate across the KCNB2 rs349358 polymorphisms (P>0.05). The CHRM3 rs2165870 polymorphism is associated with the occurrence of postoperative vomiting in female patients who have undergone laparoscopic surgery. The AA genotype or A allele of the CHRM3 rs2165870 polymorphism elevates the risk of postoperative vomiting. www.chictr.org.cn, registration number: ChiCTR2200062425.

Preoperative bedside test indicators as predictors of difficult video laryngoscopy in obese patients: a prospective observational study.

The aim of this study was to identify factors associated with difficult video laryngoscopy in obese patients. A total of 579 obese patients undergoing elective laparoscopic weight loss surgery were intubated with a single-lumen endotracheal tube using a video laryngoscopy under general anesthesia, and the patients were divided into two groups based on the Cormack-Lehane classification (difficult video laryngoscopy defined as ≥ 3): the easy video laryngoscopy group and the difficult video laryngoscopy group. Record the general condition of the patient, bedside testing indicators related to the airway, Cormack-Lehane classification during intubation, and intubation failure rate. The findings of this study show that the incidence of difficult video laryngoscopy in obese patients is 4.8%. Multivariate logistic regression analysis indicated that body mass index was significantly associated with difficult video laryngoscopy (OR = 1.082, 95% CI [1.033-1.132], P<0.001). For Chinese obese patients without known difficult airways, the incidence of difficult video laryngoscopy is 4.8%. Body mass index is associated factors for the occurrence of difficult video laryngoscopy, with an increased risk observed as body mass index rise.

Predictive value of preoperative ultrasonographic measurement of gastric morphology for the occurrence of postoperative nausea and vomiting among patients undergoing gynecological laparoscopic surgery.

Pre-operative prediction of postoperative nausea and vomiting (PONV) is primarily based on the patient's medical history. The predictive value of gastric morphological parameters observed on ultrasonography has not been comprehensively assessed. A prospective observational study was conducted to evaluate the pre-operative ultrasonographic measurement of gastric morphology for predicting PONV. The gastric antrum of the participants was assessed using ultrasound before anesthesia, and the occurrence of PONV in the first 6 hours and during the 6-24 hours after surgery was reported. The main indicators included the thickness of the muscularis propria (TMP) and the cross-sectional area of the inner side of the muscularis propria (CSA-ISMP). These were recorded and analyzed. Logistic regression analysis was applied to identify factors for PONV. A total of 72 patients scheduled for elective gynecological laparoscopic surgery were investigated in the study. The pre-operative CSA-ISMP of patients with PONV in the first 6 hours was significantly greater than that of those without PONV (2.765 ± 0.865 cm² vs 2.349 ± 0.881 cm², P=0.0308), with an area under the curve of 0.648 (95% CI, 0.518 to 0.778, P=0.031). Conversely, the pre-operative TMP of patients with PONV during the 6-24 hours was significantly smaller than that of those without PONV (1.530 ± 0.473mm vs 2.038 ± 0.707mm, P=0.0021), with an area under the curve of 0.722 (95% CI, 0.602 to 0.842, P=0.003). Logistic regression analysis confirmed that CSA-ISMP was an independent risk factor for PONV in the first 6 hours (OR=2.986, P=0.038), and TMP was an independent protective factor for PONV during the 6-24 hours after surgery (OR=0.115, P=0.006). Patients with a larger pre-operative CSA-ISMP or a thinner TMP are prone to develop PONV in the first 6 hours or during the 6-24 hours after surgery, respectively. http://www.chictr.org.cn (ChiCTR2100055068).

Effect of Intraoperative Lung Recruitment and Transversus Abdominis Plane Block in Laparoscopic Bariatric Surgery on Postoperative Lung Functions: A Randomized Controlled Study

Abstract Background Morbid obesity may cause a restrictive condition. general anesthesia (GA) and supine posture both result in a decrease in lung capacity and Functional residual capacity (FRC), encouraging the development of atelectasis, altering the ventilation/perfusion ratio and raising the pulmonary shunt. This study evaluated the impact of recruitment maneuver (RM) and Transversus Abdominis Plane (TAP) block performed during laparoscopic bariatric surgery on spirometry, oxygenation, hemodynamic variables, opioid requirements and pain score assessed after surgery. Methods This pilot prospective randomized controlled study included 80 patients scheduled for elective laparoscopic bariatric surgeries (e.g., laparoscopic sleeve gastrectomy, and laparoscopic gastric bypass) under GA. Patients were divided into four equal groups. All patients had received standardized postoperative analgesia regimen, group I (control group), group II received TAP block after intubation and before surgical incision, group III received RM after intubation and after pneumoperitoneal exsufflation, and group IV received RM after intubation and after pneumoperitoneal exsufflation and TAP block after intubation and before surgical incision. Results Forced Vital Capacity “FVC”, Forced Expiratory Volume “FEV1” were found to be significantly higher after operation in group IV compared to other groups. FEV1/FVC was insignificantly different among the four groups before and after operation. Intraoperative PaO2, PaO2/FiO2 were significantly higher in group III and IV compared to other groups. Numerical rating scale (NRS) at 1, 2, 4, 6 and 12hr had significantly decreased in group II and IV compared to other groups. Heart rate (HR) and mean arterial blood pressure (MAP) were insignificantly different among the four groups. Morphine consumption was significantly lower in group II and IV compared to other groups. Conclusions TAP block combined with RM group exhibited better postoperative pulmonary function tests (PFTs). Intraoperative oxygenation was higher in RM groups. NRS and opioid consumption were lower in TAP groups in postoperative period.

Midazolam versus Ondansetron versus Dexamethasone in Preventing Post-Operative Nausea and Vomiting after Elective Laparoscopic Abdominal Surgeries

Abstract Background Laparoscopic surgery is associated with a remarkably high risk of post-operative nausea and vomiting. The reasons for this high rate of PONV include mechanical factors (such as pressure on the stomach and gut caused by the pneumoperitoneum), neural factors (such as vagal reflexes elicited by irritation of parasympathetic nerve endings in the abdomen), and chemical factors (which include speculative considerations regarding a possible influence of CO2 on PONV). Objective To compare the effect of midazolam, ondansetron or dexamethasone on prophylaxis against PONV in patients undergoing laparoscopic abdominal surgeries. Patients and Methods After approval of anesthesiology department, scientific and ethical committees in Ain Shams University Hospitals, patients were included in the study, and were divided into three groups (n = 40; each); group M (midazolam group) and Group O (ondansetron group) and group D (dexamethasone group). Results The three groups were adequately monitored and assessed post-operatively and they were compared regarding post-operative nausea and vomiting outcome by recording the incidence of nausea and vomiting and recording the call for rescue antiemetic. Demographic data, intra-operative hemodynamics and post-operative pain score, occurrence of side effects, sedation score and patient satisfaction scores were also assessed, we found about 95% of (M) group achieve the complete response, that mean midazolam provided PONV prophylaxis comparable to dexamethasone and ondansetron in patients who underwent laparoscopic abdominal surgeries. Conclusion From this study, we can conclude that the midazolam is as effective as ondansetron and dexamethasone in reducing the incidence of nausea and vomiting in post-operative period of laparoscopic abdominal surgeries.

Ultrasound-Guided Quadratus Lumborum Block Using Bupivacaine versus Bupivacaine – Dexamethasone as Postoperative Analgesia in Laparoscopic Cholecystectomy

Abstract Background The QLB is an effective analgesic technique for various abdominal wall incisions. The QLB covers T7 to L2 dermatomes by the spread of LA drugs either into the paravertebral space or in the thoracolumbar plane, through iliohypogastric and ilioinguinal nerves, A and C fiber nociceptors, mechanoreceptors and high-density network of lumbar sympathetic fibers. Objective To assess the analgesic sparing effect of adding Dexamethasone to Bupivacaine in Quadratus lumborum block in patients undergoing Laparoscopic cholecystectomy under general anesthesia. Patients and Methods Sixty patients scheduled for elective Laparoscopic cholecystectomy surgeries under general anesthesia were included in this study, they were divided into two groups. Group A (perineural dexamethasone and bupivacaine group) [n = 30] Those cases will receive 2ml volume of dexamethasone (8mg) combined with 18 ml of bupivacaine of 0.25% concentration. Group B (perineural bupivacaine group) [n = 30] Those cases will receive perineural 18 ml bupivacaine (0.25%) combined with 2 ml normal saline. Results At the end of this study we found that The addition of dexamethasone to bupivacaine in QLB in Laparoscopic cholecystectomy surgeries provides a prolonged duration of postoperative analgesia, with reduced analgesic requirements, a better quality of analgesia in terms of NRS compared to bupivacaine alone group. Conclusion The addition of dexamethasone to Bupivacaine in lateral QLB in Laparoscopic cholecystectomy surgery provides a prolonged duration of postoperative analgesia, with reduced analgesic requirements, a better quality of analgesia in terms of NRS compared to bupivacaine alone group.

Anesthesia Management of a Patient with Idiopathic Thrombocytopenic Purpura Undergoing Laparoscopic Esophageal Hiatal Hernia Surgery: A Case Report

Abstract Perioperative management of patients with immune thrombocytopenic purpura (ITP) has significant challenges for anesthesiologists. Perioperative bleeding due to thrombocytopenia in patients with ITP can be an essential challenge and is the most significant risk to anesthetists. Laparoscopic surgery can also be an additional challenge in such patients because of the risk of pneumoperitoneum that can lead to hemodynamic instability and bleeding deterioration. We present a 77-year-old successful anesthesia management of a female patient with ITP who underwent elective laparoscopic esophageal hiatal hernia surgery. A multidisciplinary team approach and comprehensive perioperative assessment and treatment are critical to ensure successful perioperative management of patients with ITP. We also aim to suggest that intravenous immunoglobulins therapy is not always mandatory in perioperative management of patients with ITP.

Perioperative liberal drinking management promotes postoperative gastrointestinal function recovery after gynecological laparoscopic surgery: A randomized controlled trial

Study objectiveThis study aims to evaluate the effect of perioperative liberal drinking management, including preoperative carbohydrate loading (PCL) given 2 h before surgery and early oral feeding (EOF) at 6 h postoperatively, in enhancing postoperative gastrointestinal function and improving outcomes in gynecologic patients. The hypotheses are that the perioperative liberal drinking management accelerates the recovery of gastrointestinal function, enhances dietary tolerance throughout hospitalization, and ultimately reduces the length of hospitalization. DesignA prospective randomized controlled trial. SettingOperating room and gynecological ward in Wuhan Union Hospital. PatientsWe enrolled 210 patients undergoing elective gynecological laparoscopic surgery, and 157 patients were included in the final analysis. InterventionsPatients were randomly allocated in a 1:1:1 ratio into three groups, including the control, PCL, and PCL-EOF groups. The anesthetists and follow-up staff were blinded to group assignment. MeasurementsThe primary outcome was the postoperative Intake, Feeling nauseated, Emesis, Examination, and Duration of symptoms (I-FEED) score (range 0 to 14, higher scores worse). Secondary outcomes included the incidence of I-FEED scores >2, and other additional indicators to monitor postoperative gastrointestinal function, including time to first flatus, time to first defecation, time to feces Bristol grade 3–4, and time to tolerate diet. Additionally, we collected other ERAS recovery indicators, including the incidence of PONV, complications, postoperative pain score, satisfaction score, and the quality of postoperative functional recovery at discharge. Main resultsThe PCL-EOF exhibited significantly enhanced gastrointestinal function recovery compared to control group and PCL group (p < 0.05), with the lower I-FEED score (PCL: 0[0,1] vs. PCL-EOF: 0[0,0] vs. control: 1[0,2]) and the reduced incidence of I-FEED >2 (PCL:8% vs. PCL-EOF: 2% vs. control:21%). Compared to the control, the intervention of PCL-EOF protected patients from the incidence of I-FEED score > 2 [HR:0.09, 95%CI (0.01–0.72), p = 0.023], and was beneficial in promoting the patient's postoperative first flatus [PCL-EOF: HR:3.33, 95%CI (2.14–5.19),p < 0.001], first defecation [PCL-EOF: HR:2.76, 95%CI (1.83–4.16), p < 0.001], Bristol feces grade 3–4 [PCL-EOF: HR:3.65, 95%CI (2.36–5.63), p < 0.001], first fluid diet[PCL-EOF: HR:2.76, 95%CI (1.83–4.16), p < 0.001], and first normal diet[PCL-EOF: HR:6.63, 95%CI (4.18–10.50), p < 0.001]. Also, the length of postoperative hospital stay (PCL-EOF: 5d vs. PCL: 6d and control: 6d, p < 0.001), the total cost (PCL-EOF: 25052 ± 3650y vs. PCL: 27914 ± 4684y and control: 26799 ± 4775y, p = 0.005), and postoperative VAS pain score values [POD0 (PCL-EOF: 2 vs. control: 4 vs. PCL: 4, p < 0.001), POD1 (PCL-EOF: 1 vs. control: 3 vs. PCL: 2, p < 0.001), POD2 (PCL-EOF: 1 vs. control:2 vs. PCL: 1, p < 0.001), POD3 (PCL-EOF: 0 vs. control: 1 vs. PCL: 1, p < 0.001)] were significantly reduced in PCL-EOF group. ConclusionsOur primary endpoint, I-FEED score demonstrated significant reduction with perioperative liberal drinking, serving as a protective intervention against I-FEED>2. Gastrointestinal recovery metrics, such as time to first flatus and defecation, also showed substantial improvements. Furthermore, the intervention enhanced postoperative dietary tolerance and expedited early recovery.Trial registration: ChiCTR2300071047(https://www.chictr.org.cn/).
