Dual Toxidrome of Anti-cholinergic Storm and Neuroleptic Malignant Syndrome: A Therapeutic Challenge Overcome by Intrathecal Neostigmine.

Anticholinergic toxicity and neuroleptic malignant syndrome (NMS) are common toxidromes in medical emergencies. However, their co-occurrence, resulting in a dual toxidrome, is rare and presents significant diagnostic and therapeutic challenges. We present the case of a 23-year-old young male with polysubstance dependence, admitted following combined trihexyphenidyl and risperidone toxicity. He was diagnosed with a dual toxidrome of anticholinergic storm and NMS. Treatment of NMS included lorazepam and bromocriptine. Due to the unavailability of physostigmine, the preferred antidote for anticholinergic syndrome, intrathecal neostigmine was administered. The patient subsequently recovered and was discharged. This case highlights the complexity of managing dual toxidromes and the need for alternative therapeutic strategies in resource-limited settings.

Influence of Anticholinesterase Drugs on Activity and Properties of Na+,K+-ATPase in Rat Erythrocytes under Stress Caused by Intense Physical Exercise.

We studied the effect of intramuscular injection of physostigmine and neostigmine on Na+,K+-ATPase activity in erythrocytes of rats subjected to intense physical exercise. Both anticholinesterase drugs had a significant effect on the development of the stress response, which was expressed in a decrease in the manifestation of its individual components such as the concentration of ascorbic acid in the adrenal glands, stress-related erythrocyte polycythemia, and LPO indicators. Anticholinesterase drugs reverse the stress-induced decrease in Na+,K+-ATPase activity, as well as changes in its magnesium-dependent properties. There were no changes in the activity of the studied enzyme in the erythrocyte ghosts. We associate the observed differences with the correction of the functions of the cholinergic components of the hypothalamic-pituitary-adrenal axis leading to the development of a hypoergic type stress reaction.

Sugammadex vs Neostigmine, a Comparison in Reversing Neuromuscular Blockade: A Narrative Review.

The use of neuromuscular blocking agents (NMBA) has grown due to the development of laparoscopic and minimally invasive procedures. Respiratory insufficiency, an elevated risk of aspiration, postoperative pulmonary complications, and subsequent reintubation are among the risks linked to the residual block. The normal clinical practice calls for the pharmacologic "reversal" of these agents with either sugammadex or neostigmine prior to extubation. The administration of neostigmine is linked to a number of potential complications. In response, anaesthesiologists have begun to prescribe sugammadex more frequently for treating residual block and reversing blockade with NMBA. This review article compares and assesses neostigmine and sugammadex thoroughly in order to determine the extent to which they work as agents to reverse neuromuscular blockade. The review's findings highlight sugammadex's considerable advantages - Sugammadex's ability to quickly and reliably achieve desired train-of-four (TOF) ratios - over neostigmine in reversing neuromuscular blockade in a variety of surgical settings. In contrast, neostigmine's limitations regarding efficacy and rate of reversal were consistently noted in all of the reviewed studies, despite the fact that it is still widely used due to its lower cost and extensive clinical experience. Sugammadex is a superior option for reversing neuromuscular blockade, but incorporating it into standard clinical practice necessitates carefully weighing its potential benefits and drawbacks. Sugammadex provides notable benefits over neostigmine in terms of speed, predictability, and safety.

Factors Influencing Neuromuscular Blockade Reversal Choice in the United States Before and During the COVID-19 Pandemic: Retrospective Longitudinal Analysis.

BACKGROUND: Neuromuscular blockade (NMB) agents are a critical component of balanced anesthesia. NMB reversal methods can include spontaneous reversal, sugammadex, or neostigmine and the choice of reversal strategy can depend on various factors. Unanticipated changes to clinical practice emerged due to the COVID-19 pandemic, and a better understanding of how NMB reversal trends were affected by the pandemic may help provide insight into how providers view the tradeoffs in the choice of NMB reversal agents. OBJECTIVE: We aim to analyze NMB reversal agent use patterns for US adult inpatient surgeries before and after the COVID-19 outbreak to determine whether pandemic-related practice changes affected use trends. METHODS: A retrospective longitudinal analysis of a large all-payer national electronic US health care database (PINC AI Healthcare Database) was conducted to identify the use patterns of NMB reversal during early, middle, and late COVID-19 (EC, MC, and LC, respectively) time periods. Factors associated with NMB reversal choices in inpatient surgeries were assessed before and after the COVID-19 pandemic reached the United States. Multivariate logistic regression assessed the impact of the pandemic on NMB reversal, accounting for patient, clinical, procedural, and site characteristics. A counterfactual framework was used to understand if patient characteristics affected how COVID-19-era patients would have been treated before the pandemic. RESULTS: More than 3.2 million inpatients experiencing over 3.6 million surgical procedures across 931 sites that met all inclusion criteria were identified between March 1, 2017, and December 31, 2021. NMB reversal trends showed a steady increase in reversal with sugammadex over time, with the trend from January 2018 onwards being linear with time (R2>0.99). Multivariate analysis showed that the post-COVID-19 time periods had a small but statistically significant effect on the trend, as measured by the interaction terms of the COVID-19 time periods and the time trend in NMB reversal. A slight increase in the likelihood of sugammadex reversal was observed during EC relative to the pre-COVID-19 trend (odds ratio [OR] 1.008, 95% CI 1.003-1.014; P=.003), followed by negation of that increase during MC (OR 0.992, 95% CI 0.987-0.997; P<.001), and no significant interaction identified during LC (OR 1.001, 95% CI 0.996-1.005; P=.81). Conversely, active reversal (using either sugammadex or neostigmine) did not show a significant association relative to spontaneous reversal, or a change in trend, during EC or MC (P>.05), though a slight decrease in the active reversal trend was observed during LC (OR 0.987, 95% CI 0.983-0.992; P<.001). CONCLUSIONS: We observed a steady increase in NMB active reversal overall, and specifically with sugammadex compared to neostigmine, during periods before and after the COVID-19 outbreak. Small, transitory alterations in the NMB reversal trends were observed during the height of the COVID-19 pandemic, though these alterations were independent of the underlying NMB reversal time trends.

Acute Intestinal Obstruction in a Case of Cerebrovascular Accident.

Ogilvie's syndrome represents an acute form of intestinal obstruction that occurs in the absence of a detectable mechanical blockage impeding fecal passage. Hence, it is also given the name of intestinal pseudo-obstruction. It has been deemed a disease of imbalance between the arms of the autonomic nervous system with an increase in parasympathetic outflow. Most often, it has an antecedent surgical or medical illness. There is evidence for the use of IV neostigmine in such cases to prevent imminent intestinal ischemia and perforation. In the case of a non-responder, decompression of the bowel using a colonoscope and surgery have also been tried to relieve the symptoms. In the case that follows, a middle-aged man developed progressive abdominal distension in the course of his recovery from an ischemic cerebrovascular accident. Initially, he received conservative treatment for 48 hours. Subsequently, he was given IV neostigmine, which relieved his symptoms.

A Case of Congenital Myasthenia Gravis due to ChAT Gene Mutation in a Term Neonate: A Case Report.

Congenital myasthenia gravis syndrome (CMS) is a rare genetic heterogeneous disorder due to abnormal neuromuscular transmission caused by several genes. CMS caused by choline acetyltransferase (ChAT) gene mutations have been reported in 53 cases since 2020, and only three of them have been identified as hemizygous mutations. A 1-day-old term neonate was transferred from the nursery to the neonatal intensive care unit on 10 L of oxygen by face mask due to respiratory distress. Family history includes two ChAT gene variants in the elder brother and carrier genes in both parents. She was transitioned to continuous positive airway pressure +5, and chest X-ray showed poor chest expansion. Sepsis workup was negative. She was intubated due to worsening respiratory distress 3 days later. She was started on pyridostigmine, and genetic testing was done, which confirmed two ChAT gene mutations present. The patient had a tracheostomy placed on day 50 and was discharged on day 94 of life on tracheostomy and G-tube, given feeding intolerance. This case illustrates the value of genetic testing in determining the type of CMS to guide management and the importance of obtaining family history to have such syndromes earlier in the differential diagnosis to initiate treatment promptly.

Reversal of neuromuscular block with neostigmine and sugammadex: a retrospective cohort study in two centers using different types of neuromuscular monitoring.

This bicentric retrospective cohort study evaluates reversal of muscle relaxation in real life achieved either by neostigmine or sugammadex in two hospitals using different types of neuromuscular monitoring (acceleromyography and kinemyography). The research question concerns compliance with recommendations. Patients who underwent an abdominal surgery under general anesthesia in the period from January 2017 through December 2020 with a neuromuscular block with rocuronium were included in the study. Data were extracted from the Centricity anesthesia information management system. In total, 2242 patients were assessed: 459 in center 1 (61 having received neostigmine and 398 sugammadex) and 1783 in center 2 (531 and 1252, respectively). Patients' characteristics differed between centers, with more high-risk patients in center 1. The mean train-of-four (TOF) ratio after supramaximal current determination (supramaximal threshold) was higher in center 1 (p < 0.001). Most patients received neostigmine while the TOF ratio was < 40% (68.6% in center 1 and 62.4% in center 2), while extubation was performed while the TOF ratio was > 90% in 61.0% in center 1 and in 32.1% in center 2 (p < 0.001). Patients received sugammadex irrespective of the number of responses to TOF before reversal, and extubation was performed while the TOF ratio was > 90% in 85.0% in center 1 and in 53.6% in center 2 (p < 0.001). No side effect was encountered. Despite guidelines for the TOF ratio before extubation, recommendations were not adequately respected and more vigilance is mandatory. The TOF test before use gave values that were 100% far apart with an underestimation with acceleromyography and an overestimation using kinemyography.

Postpartum Ogilvie's Syndrome After a Vaginal Delivery.

Ogilvie's syndrome is a colonic pseudo-obstruction that results in colonic dilation without a mechanical obstruction. We discuss a 33-year-old, 36-week pregnant, G1P0L0A0 female who presented with severe pre-eclampsia. Less than 24 hours after induction by vaginal delivery, she developed significant abdominal pain and distention. On a CT scan of the abdomen and pelvis, she was diagnosed with Ogilvie's syndrome due to a finding of large bowel dilation with an abrupt transition point at the splenic flexure without a noted mass. She was initially treated conservatively with nasogastric tube decompression and IV fluid resuscitation. When these conservative measures failed, neostigmine was administered with transient improvement in symptoms. Despite the appropriate administration of neostigmine and initial relief of symptoms with stool output, the patient ultimately required surgical intervention with the creation of a transverse loop colostomy. The development of Ogilvie's syndrome in the postpartum period is a very rare finding, particularly after a vaginal delivery.

Effect of coadministration of 10 mg/kg calcium chloride and neostigmine on extubation time: A randomized controlled trial.

INTRODUCTION AND OBJECTIVES: Some studies investigating the effect of calcium on neostigmine-induced recovery of neuromuscular blockade have shown that this combination promotes neuromuscular recovery, but does not significantly affect the incidence of postoperative residual curarization and time to extubation. This study aimed to evaluate the effects of 10 mg/kg calcium chloride co-administered with neostigmine on early recovery and time to extubation. PATIENTS AND METHODS: This prospective, randomized, double-blinded, placebo-controlled study included 88 ASA I-II patients aged between 18 and 65 years who were scheduled for elective surgery lasting at least 1 h under general anaesthesia in which 10 mg/kg of calcium chloride or the same volume of normal saline was co-administered with 5 µg/kg of neostigmine at the end of surgery. Time to extubation (time from neostigmine administration to extubation), time from neostigmine administration to TOF ratio (TOFr) 0.9 (neuromuscular recovery), and the incidence of residual neuromuscular blockade (RNMB) and other adverse effects were recorded. RESULTS: Median (Q1, Q3) extubation time was significantly shorter in the calcium group vs. the placebo group (6.5 min [5.52-7.43] vs. 9.78 min [8.35-11]), P < .001. Median neuromuscular recovery time in the calcium group was 5 min vs. 7.1 min in the placebo group, P < .001. Patients in the calcium group had significantly higher TOFr and lower incidence of RNMB at 5 and 10 min vs. the placebo group, and no significant side effects. CONCLUSION: Calcium chloride at a dose of 10 mg/kg co-administered with neostigmine promotes early neuromuscular recovery and reduces time to extubation by about 32%.

The effect of glycopyrrolate vs. atropine in combination with neostigmine on cardiovascular system for reversal of residual neuromuscular blockade in the elderly: a randomized controlled trial.

BACKGROUND: Glycopyrrolate-neostigmine (G/N) for reversing neuromuscular blockade (NMB) causes fewer changes in heart rate (HR) than atropine-neostigmine (A/N). This advantage may be especially beneficial for elderly patients. Therefore, this study aimed to compare the cardiovascular effects of G/N and A/N for the reversal of NMB in elderly patients. METHODS: Elderly patients aged 65-80 years who were scheduled for elective non-cardiac surgery under general anesthesia were randomly assigned to the glycopyrrolate group (group G) or the atropine group (group A). Following the last administration of muscle relaxants for more than 30 min, group G received 4 ug/kg glycopyrrolate and 20 ug/kg neostigmine, while group A received 10 ug/kg atropine and 20 ug/kg neostigmine. HR, mean arterial pressure (MAP), and ST segment in lead II (ST-II) were measured 1 min before administration and 1-15 min after administration. RESULTS: HR was significantly lower in group G compared to group A at 2-8 min after administration (P < 0.05). MAP was significantly lower in group G compared to group A at 1-4 min after administration (P < 0.05). ST-II was significantly depressed in group A compared to group G at 2, 3, 4, 5, 6, 7, 8, 9, 11, 13, 14, and 15 min after administration (P < 0.05). CONCLUSIONS: In comparison to A/N, G/N for reversing residual NMB in the elderly has a more stable HR, MAP, and ST-II within 15 min after administration.

Association between reversal agents (sugammadex vs. neostigmine) for neuromuscular block and postoperative pulmonary complications: A retrospective analysis.

AIMS: Residual neuromuscular blockade has been linked to pulmonary complications in the postoperative period. This study aimed to determine whether sugammadex was associated with a lower risk of postoperative pulmonary complications (PPCs) compared with neostigmine. METHODS: This retrospective cohort study was conducted in a tertiary academic medical center. Patients ≥18 year of age undergoing noncardiac surgical procedures with general anesthesia and mechanical ventilation were enrolled between January 2019 and September 2021. We identified all patients receiving rocuronium and reversal with neostigmine or sugammadex via electronic medical record review. The primary endpoint was a composite of PPCs (including pneumonia, atelectasis, respiratory failure, pulmonary embolism, pleural effusion, or pneumothorax). The incidence of PPCs was compared using propensity score analysis. RESULTS: A total of 1786 patients were included in this study. Among these patients, 976 (54.6%) received neostigmine, and 810 (45.4%) received sugammadex. In the whole sample, PPCs occurred in 81 (4.54%) subjects (7.04% sugammadex vs. 2.46% neostigmine). Baseline covariates were well balanced between groups after overlap weighting. Patients in the sugammadex group had similar risk (overlap weighting OR: 0.75; 95% CI: 0.40 to 1.41) compared to neostigmine. The sensitivity analysis showed consistent results. In subgroup analysis, the interaction P-value for the reversal agents stratified by surgery duration was 0.011. CONCLUSION: There was no significant difference in the rate of PPCs when the neuromuscular blockade was reversed with sugammadex compared to neostigmine. Patients undergoing prolonged surgery may benefit from sugammadex, which needs to be further investigated.

Use of sugammadex in prevention of post-operative urinary retention in minimally invasive hernia surgery.

PURPOSE: Post-operative urinary retention (POUR) is a known complication of hernia surgery. Minimally invasive inguinal hernia repair (IHR) is typically done under general anesthesia with neuromuscular blockade (NMB), which is commonly reversed with an anticholinesterase inhibitor paired with an anticholinergic agent. Sugammadex is a unique NMB reversal agent that does not have to be paired with an anticholinergic. We sought to explore the role of sugammadex in reducing the rate of POUR following these procedures. METHODS: Data were collected retrospectively at a single institution between February 2016 and October 2019. We identified and studied patients who underwent minimally invasive IHR and received either sugammadex or neostigmine/glycopyrrolate for NMB reversal. The primary endpoint was POUR requiring bladder catheterization. Secondary endpoints included post-operative and 30-day readmissions. RESULTS: 274 patients were included in this study (143 received neostigmine and glycopyrrolate, 131 sugammadex). The sugammadex patients were on average 5 years older than the neostigmine/ glycopyrrolate patients (63.2 vs 58.2, p = 0.003), and received less median intravenous fluids (IVF) (900 ml vs 1000 ml; p = 0.015). There was a significant difference in the rate of POUR between the sugammadex and neostigmine/glycopyrrolate patients (0.0% vs 8.4%, p ≤ 0.001). The difference remained significant after controlling for age and IVF. The odds of POUR for those who received neostigmine/glycopyrrolate were 25 × higher than the odds of those who received sugammadex. CONCLUSION: The results of this study reflect the protective role of sugammadex against POUR in minimally invasive IHR cases.

Decurarization After Thoracic Anesthesia using sugammadex compared to neostigmine (DATA trial): a multicenter randomized double-blinded controlled trial.

BACKGROUND: Thoracic surgery is a high-risk surgery especially for the risk of postoperative pulmonary complications. Postoperative residual paralysis has been shown to be a risk factor for pulmonary complications. Nevertheless, there are few data in the literature concerning the use of neuromuscular blocking agent antagonists in patients undergoing lung surgery. METHODS: Seventy patients were randomized in three Italian centers to receive sugammadex or neostigmine at the end of thoracic surgery according to the depth of the residual neuromuscular block. The primary outcome was the time from reversal administration to a train-of-four ratio (TOFR) of 0.9. Secondary outcomes were the time to TOFR of 1.0, to extubation, to postanesthesia unit (PACU) discharge, postoperative complications until 30 days after surgery, and length of hospital stay. RESULTS: Median time to recovery to a TOFR of 0.9 was significantly shorter in the sugammadex group compared to the neostigmine one (88 vs. 278 s - P < 0.001). The percentage of patients who recovered to a TOFR of 0.9 within 5 min from reversal administration was 94.4% and 58.8% in the sugammadex and neostigmine groups, respectively (P < 0.001). The time to extubation, but not the PACU stay time, was significantly shorter in the sugammadex group. No differences were found between the study groups as regards postoperative complications and length of hospital stay. The superiority of sugammadex in shortening the recovery time was confirmed for both deep/moderate and shallow/minimal neuromuscular block. CONCLUSIONS: Among patients undergoing thoracic surgery, sugammadex ensures a faster recovery from the neuromuscular block and earlier extubation compared to neostigmine.

Post-operative urinary retention is impacted by neuromuscular block reversal agent choice: A retrospective cohort study in US hospital setting.

STUDY OBJECTIVE: Perioperative neuromuscular blocking agents are pharmacologically reversed to minimize complications associated with residual neuromuscular block. Neuromuscular block reversal with anticholinesterases (e.g., neostigmine) require coadministration of an anticholinergic agent (e.g., glycopyrrolate) to mitigate muscarinic activity; however, sugammadex, devoid of cholinergic activity, does not require anticholinergic coadministration. Single-institution studies have found decreased incidence of post-operative urinary retention associated with sugammadex reversal. This study used a multicenter database to better understand the association between neuromuscular block reversal technique and post-operative urinary retention. DESIGN: Retrospective cohort study utilizing large healthcare database. SETTING: Non-profit, non-governmental and community and teaching hospitals and health systems from rural and urban areas. PATIENTS: 61,898 matched adult inpatients and 95,500 matched adult outpatients. INTERVENTIONS: Neuromuscular block reversal with sugammadex or neostigmine plus glycopyrrolate. MEASUREMENTS: Incidence of post-operative urinary retention by neuromuscular block reversal agent and the independent association of neuromuscular block reversal technique and risk of post-operative urinary retention. MAIN RESULTS: The incidence of post-operative urinary retention was 2-fold greater among neostigmine with glycopyrrolate compared to sugammadex patients (5.0% vs 2.4% inpatients; 0.9% vs 0.4% outpatients; both p < 0.0001). Multivariable logistic regression identified reversal with neostigmine to be independently associated with greater risk of post-operative urinary retention (inpatients: odds ratio, 2.20; 95% confidence interval, 2.00 to 2.41; p < 0.001; outpatients: odds ratio, 2.57; 95% confidence interval, 2.13 to 3.10; p < 0.001). Post-operative urinary retention-related visits within 2 days following discharge were five-fold higher among those reversed with neostigmine than sugammadex among inpatients (0.05% vs. 0.01%, respectively; p = 0.018) and outpatients (0.5% vs. 0.1%; p < 0.0001). CONCLUSION: Though this study suggests that neuromuscular block reversal with neostigmine can increase post-operative urinary retention risk, additional studies are needed to fully understand the association.

Neostigmine and atropine as a treatment for postdural puncture headache after spinal anesthesia in cesarean section: A case report.

Key Clinical message: Neostigmine and atropine offer a promising treatment option for postdural puncture headache (PDPH) following spinal anesthesia in cesarean section, providing effective relief with a favorable risk-benefit profile. Abstract: Postdural puncture headache (PDPH) is a common consequence of cesarean section surgeries after spinal anesthesia. This case study describes the successful treatment of PDPH with intravenous neostigmine and atropine. A 31 years female who underwent elective cesarean section with spinal anesthesia developed a severe headache on the 6th postoperative day and was diagnosed to have PDPH. PDPH failed to respond to conventional treatment modalities like hydration, a Non-steroidal anti-inflammatory drug, and sphenopalatine ganglion block. Epidural blood patch could not be performed due to lack of consent. A trial dose of intravenous neostigmine (20 mcg/kg) along with atropine (10 mcg/kg) successfully provided symptomatic and clinical relief. The combination of neostigmine and atropine demonstrates a rapid onset of action, providing patients with effective analgesia while avoiding the need for invasive procedures such as epidural blood patches and offers quicker pain relief. This promising result warrants additional research.

[Nutrition (therapy) in gastrointestinal failure]. / Gastrointestinales Versagen ­ Ernährung bei Reflux und Darmatonie.

BACKGROUND: The presence of gastrointestinal dysfunction is an outcome-relevant complication in critically ill ICU patients. AIMS, MATERIALS AND METHODS: The following review aims to show the importance of gastrointestinal dysfunction. Multimodal therapy for gastroparesis and paralytic ileus is discussed. CONCLUSION: Erythromycin and metoclopramide are options for gastroparesis, while neostigmine is commonly used for paralytic ileus.

Sugammadex and blood loss during cervical spine fusion surgery.

Background and Aims: Sugammadex (SUG) has been associated with changes in coagulation studies. Most reports have concluded a lack of clinical significance based on surgical blood loss with SUG use at the end of surgery. Previous reports have not measured its use intraoperatively during ongoing blood loss. Our hypothesis was that the use of SUG intraoperatively may increase bleeding. Material and Methods: This was a single site retrospective study. Inclusion criteria were patients undergoing a primary posterior cervical spine fusion, aged over 18 years, between July 2015 and June 2021. The primary outcomes compared were intraoperative estimated blood loss (EBL) and postoperative drain output (PDO) between patients receiving SUG, neostigmine (NEO) and no NMB reversal agent. The objective was to determine if there was a difference in primary endpoints between patients administered SUG, NEO or no paralytic reversal agent. Primary endpoints were compared using analysis of variance with a P value of 0.05 used to determine statistical significance. Groups were compared using the Chi-squared test, rank sum or student's t test. A logistic regression model was constructed to account for differences between the groups. Results: There was no difference in median EBL or PDO between groups. The use of SUG was not associated with an increase in odds for >500 milliliters (ml) of EBL. Increasing duration of surgery and chronic kidney disease were both associated with an increased risk for EBL >500 ml. Conclusion: Intraoperative use of SUG was not associated with increased bleeding. Any coagulation laboratory abnormalities previously noted did not appear to have an associated clinical significance.

The effect of sugammadex on postoperative urinary retention post-laparoscopic and robotic hysterectomy with and without concomitant procedures.

INTRODUCTION AND HYPOTHESIS: This study was aimed at determining the effect of sugammadex versus a combination of glycopyrrolate and neostigmine (GN) for neuromuscular reversal blockage on transient postoperative urinary retention (TPOUR) in patients undergoing a laparoscopic and robot-assisted laparoscopic hysterectomy. METHODS: We conducted a retrospective cohort study in patients undergoing a laparoscopic or robotic hysterectomy between February 2017 and December 2021. Patients with and without concomitant procedures were included. Demographics and perioperative data were extracted from the patient's medical record. Before discharge, all patients were required to spontaneously void and have a post-void residual of less than 150 ml. RESULTS: We identified 500 patients and 485 were included in the final analysis. We had 319 subjects who received sugammadex and 166 GN combination. Both groups had overall similar demographics and perioperative characteristics. Most patients had a conventional laparoscopy procedure (391 [82.5%]) compared with robotic (83 [17.5%]). Patients who received GN were significantly more likely to be discharged home with an indwelling catheter (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.09-3.05). After adjusting for perioperative medications and sling implantation during the surgery a logistic regression model continued to demonstrate that patients who received GN had significantly higher odds of being discharged with a catheter (OR, 1.79; 95% CI, 1.03-3.12). CONCLUSIONS: Our findings suggest that sugammadex decreases the odds of TPOUR after laparoscopic hysterectomies with and without slings compared with the combination of GN. Additional prospective trials are required to confirm this finding.
