Background: To discuss whether decreasing the pressure of endotracheal tube cuff slowly with a constant speed can decrease the incidence of coughing during extubation.

Methods: Ninety patients undergoing elective noncardiac surgery under general anesthesia with endotracheal intubation were randomly divided into two groups: group P, the pilot balloon was connected to a syringe and an aneroid manometer through a three-way stopcock, respectively, and the decrease of cuff pressure was controlled at 3 cmH₂O/s during deflating before extubation; group C, the pressure in endotracheal tube cuff was decreased suddenly with a syringe extracting the air from the cuff rapidly at once exactly before extubation. The incidence of coughing during extubation period was recorded. Mean arterial pressure (MAP) and heart rate (HR) were recorded before general anesthesia induction (T0), just before cuff deflation (T1), immediately after deflation (T2), at 1 min (T3), 3 min (T4), and 5 min after extubation (T5). The occurrence of adverse reactions was also recorded.

Results: The initiation of coughing during extubation period occurs at immediately the time of balloon deflation. Compared with group C, the incidence of coughing was significantly decreased (P = 0.001), MAP and HR were significantly decreased at T2-T4 and T2-T5, respectively (P < 0.05 for all), and the incidence of pharyngolaryngeal discomfort after extubation was significantly reduced (P = 0.021) in group P.

Conclusions: Decreasing the pressure of endotracheal tube cuff slowly with a constant speed can significantly reduce the incidence of coughing during extubating period, stabilize hemodynamics, and reduce the incidence of adverse reactions.

Objective: To evaluate effects of intraoperative magnesium sulfate infusion on pain control and analgesic use in the postanesthesia care unit (PACU).

Methods: This is a retrospective review of patients undergoing robot-assisted radical prostatectomy (RARP) and endoscopic procedures of the bladder, prostate, and urethra from 2/2021 to 12/2021. Patients receiving Mg infusion (Mg group) received an intravenous 2-g bolus of Mg at anesthesia induction, followed by infusion of 1 g/h until procedure end. Outcomes were compared with patients who underwent similar procedures during this timeframe without Mg (Control). Endpoints were use of anticholinergic (AC) and belladonna and opium suppositories (BO), maximum pain score, and morphine milligram equivalents (MME) in PACU.

Results: There were 182 patients, with 89 (48.9%) patients in the Mg group and 93 (51.1%) in the Control. Significantly, fewer patients in the Mg group were given AC/BO in PACU (9.0% vs. 21.7%, p = 0.02), with odds of using AC/BO which was 0.36 (95% CI 0.14, 0.83). No differences were found in pain score (p = 0.62) or MME administration (p = 0.94). In subgroup univariate analysis, only those who underwent bladder procedures had a significant difference in use of AC/BO (9.5% vs. 30.2%; p = 0.02). Across all surgeries, Mg infusion was associated with decreased use of AC/BO in the PACU (OR 0.34, p = 0.02); however, stratifying by procedure type did not find a difference in AC/BO use postoperatively.

Conclusion: Intravenous infusion of magnesium was found to decrease use of AC/BO in the PACU; however, this significance was lost after multivariable analysis stratifying by procedure type.

Background: Inguinal hernia repair (IHR) is a common surgical procedure worldwide. Although IHR can be performed by the minimally invasive method, which accelerates recovery, postoperative urinary retention (POUR) remains a common complication that significantly impacts patients. Thus, it is essential to identify the risk factors associated with POUR to diminish its negative impact.

Methods: We conducted a single-center retrospective review of elective IHR from 2018 to 2021. POUR was defined as the postoperative use of straight catheter or placement of an indwelling catheter to relieve the symptoms. Adjusted multivariate regression analysis was performed to address the associations of clinicodemographic, surgical, and intraoperative factors with POUR.

Results: A total of 946 subjects were included in the analysis after excluding cases of emergent surgery, recurrent hernia, or concomitant operations. The median age was 68.4 years, and 92.0% of the patients were male. Twenty-three (2.4%) patients developed POUR. In univariate analysis, POUR in comparison with non-POUR was significantly associated with increased age (72.2 versus 68.3 years, P = 0.012), a greater volume of intraoperative fluid administered (500 versus 400 ml, P = 0.040), and the diagnosis with benign prostate hypertrophy (34.8% versus 16.9%, P = 0.025). In the multivariate model, both increased age (odds ratio [OR] 1.04, 95% CI 1.01-1.08; P = 0.049) and a greater volume of intraoperative fluid administered (OR 1.12 per 100-mL increase, 95% CI 1.01-1.27; P = 0.047) were significantly associated with the occurrence of POUR.

Conclusions: We found that increased age and a greater volume of intraoperative fluid administered were significantly associated with the occurrence of POUR. Limiting the administration of intraoperative fluid may prevent POUR. From the perspective of practical implications, specific guidelines or clinical pathways should be implemented for fluid management and patient assessment.

Background: We aimed to evaluate the effects of preoperative listening to patient-preferred music and classical music on postoperative anxiety and recovery.

Methods: A prospective, randomized controlled, single-blind study included 255 patients who were scheduled for elective inguinal hernia operation under general anesthesia. Spielberger state State-Trait Anxiety Inventory form 1,2 (STAI-I, STAI-II), Quality of Recovery Score-40 (QoR-40) were applied in the preoperatively. In the preoperative period, the preferential music group (group P) patients listened to their favorite music, while patients in the classical music group (group C) listened to classical music, music was not played in the control group (group N). STAI-I, QoR-40 questionnaire, pain status, and patient satisfaction in the postoperative period were recorded by a blinded investigator.

Results: A total of 217 patients participated in the study analysis. Postoperative STAI-1 score was lower in group P than in group N (p = 0.025) and was similar among other groups. The postoperative QoR-40 score was significantly higher in group P than in group N (p = 0.003), and it was similar between the other groups. While SBP, DBP and HR premusic and post-music changes were significant, there was no difference in other groups. There was no difference between the groups in the NRS score. The patient satisfaction score was significantly higher in group P.

Conclusions: Preoperative patient-preferred music application reduces postoperative anxiety and improves recovery quality compared to classical music. In addition, regulation of hemodynamic data and patient satisfaction increase in a preferential music application, but pain scores do not change.

Background: Unplanned admission after surgery at an ambulatory surgery center (ASC) is an established measure of the quality of care and can affect the patient's experience. Previous studies on this topic are generally dated, focused on a single specialty, or studied 30-day admissions after ambulatory surgery. Few studies have reported admission within 24 h after surgery at an ASC which is a different but important measure of the quality of anesthetic and surgical care. Understanding admissions within 24 h of surgery can identify opportunities for improvement immediately after surgery. Therefore, our study was designed to assess the incidence and risk factors for unplanned hospital admissions within 24 h after surgery performed at a hospital ASC.

Methods: After Institutional Review Board approval, a retrospective analysis was performed on all adult patients who underwent surgery at a US ASC between January 1, 2016, and December 31, 2022. Data were obtained from the hospital's electronic medical record. The study sample was divided into two groups: those with an unplanned hospital admission within 24 h after surgery and those without an unplanned hospital admission. To evaluate risk factors for unplanned hospital admissions, univariate analyses with p value < 0.05 were utilized to identify significant patient variables related to hospital admissions. These variables were further adjusted using a multivariable Firth logistic regression. Descriptive statistics were used to explore the number of patients in different variable categories.

Results: Overall, 53,185 cases were identified for the 7-year period. The incidence of unplanned hospital admission over this period was 0.09% (95% CI 0.07-0.1122%; ranging from 0.05 to 0.12% per year. In the multivariable model, surgery duration (OR 1.010, 95% CI 1.007-1.012, p value < 0.0001), peripheral vascular disease (OR 14.489, 95% CI 4.862-43.174, p value < 0.0001), and deep venous thrombosis (OR 5.527, 95% CI 1.909-16.001, p value = 0.0016) were significantly associated with unplanned hospital admission.

Conclusion: The overall incidence of unplanned hospital admission after surgery at a large tertiary care ambulatory surgery center is very low. This admission rate can also serve as a reference point for future studies and quality improvement initiatives.

Background: Emergency cholecystectomy is the mainstay in treating acute cholecystitis (AC). In actual practice, perioperative prophylactic antibiotics are used to prevent postoperative infectious complications (PIC), but their effectiveness lacks evidence. We aim to investigate the efficacy of prophylactic antibiotics in emergency cholecystectomy.

Methods: We searched PubMed, Embase, Cochrane CENTRAL, Web of Science (WOS), and Scopus up to June 14, 2023. We included randomized controlled trials (RCTs) that involved patients diagnosed with mild to moderate AC according to Tokyo guidelines who were undergoing emergency cholecystectomy and were administered preoperative and/or postoperative antibiotics as an intervention group and compared to a placebo group. For dichotomous data, we applied the risk ratio (RR) and the 95% confidence interval (CI), while for continuous data, we used the mean difference (MD) and 95% CI.

Results: We included seven RCTs encompassing a collective sample size of 1747 patients. Our analysis showed no significant differences regarding total PIC (RR = 0.84 with 95% CI (0.63, 1.12), P = 0.23), surgical site infection (RR = 0.79 with 95% CI (0.56, 1.12), P = 0.19), distant infections (RR = 1.01 with 95% CI (0.55, 1.88), P = 0.97), non-infectious complications (RR = 0.84 with 95% CI (0.64, 1.11), P = 0.22), mortality (RR = 0.34 with 95% CI (0.04, 3.23), P = 0.35), and readmission (RR = 0.69 with 95% CI (0.43, 1.11), P = 0.13).

Conclusion: Perioperative antibiotics in patients with mild to moderate acute cholecystitis did not show a significant reduction of postoperative infectious complications after emergency cholecystectomy. (PROSPERO registration number: CRD42023438755).

Background: Enhanced Recovery After Surgery (ERAS) is a patient-centered approach to surgery designed to reduce stress responses and facilitate faster recovery. ERAS protocols have been widely adopted in high-income countries, supported by robust research demonstrating improved patient outcomes. However, in Africa, there is limited evidence regarding its implementation. This review aims to identify the existing literature on the implementation of ERAS principles in Africa, the reported clinical outcomes, and the challenges and recommendations for successful implementation.

Methods: We conducted a librarian-assisted literature search of electronic research databases between October and November 2023. Titles and abstracts were screened for eligibility, and duplicates were then removed, followed by full-text assessment of potentially eligible studies. We utilized the summative content analysis method to synthesize and group the data into fewer categories based on agreed-upon criteria. Descriptive statistics were used to describe the results.

Results: The search identified 342 potential studies resulting in 15 eligible studies for inclusion in the review. The publication years ranged from 2016 to 2023. The studies originated from three countries: Egypt (n = 10), South Africa (n = 4), and Uganda (n = 1). Successful implementation was associated with reduced hospital length of stay (n = 12), lower mortality rates (n = 3), and improved pain outcomes (n = 7). Challenges included protocol adherence (n = 5) and limitations of the research design to generate strong evidence (n = 3). Recommendations included formal adoption of ERAS principles (n = 5), the need for sustained research commitment, and exploration of the applicability of ERAS in diverse surgical contexts (n = 8). Large-scale implementation beyond individual institutions was encouraged to further validate its impact on patient outcomes and healthcare costs (n = 1).

Conclusions: Despite the limited number of studies on ERAS implementation in Africa, the available evidence suggests that it reduces the length of hospital stays and mortality rates. This is crucial for the region, given its higher mortality rates, necessitating more collaborative, methodically well-designed studies to establish stronger evidence for ERAS in lower-resource environments.

Background: With the popularization of robotic surgical systems in the field of surgery, robotic gastric cancer surgery has also been fully applied and promoted in China. The Chinese Guidelines for Robotic Gastric Cancer Surgery was published in the Chinese Journal of General Surgery in August 2021.

Methods: We have made a detailed interpretation of the process of robotic gastric cancer surgery regarding the indications, contraindications, perioperative preparation, surgical steps, complication, and postoperative management based on the recommendations of China's Guidelines for Robotic Gastric Cancer Surgery and supplemented by other surgical guidelines, consensus, and single-center experience.

Results: Twenty experiences of perioperative clinical management of robotic gastric cancer surgery were described in detail.

Conclusion: We hope to bring some clinical reference values to the front-line clinicians in treating robotic gastric cancer surgery.

Trial registration: The guidelines were registered on the International Practice Guideline Registration Platform ( http://www.guidelines-registry.cn ) (registration number: IPGRP-2020CN199).
