Does deep neuromuscular blockade during laparoscopy procedures change patient, surgical, and healthcare resource outcomes? A systematic review and meta-analysis of randomized controlled trials.

ABSTRACT: BACKGROUND:Deep neuromuscular blockade may facilitate the use of reduced insufflation pressure without compromising the surgical field of vision. The current evidence, which suggests improved surgical conditions compared with other levels of block during laparoscopic surgery, features significant heterogeneity. We examined surgical patient- and healthcare resource use-related outcomes of deep neuromuscular blockade compared with moderate neuromuscular blockade in adults undergoing laparoscopic surgery. METHODS:We conducted a systematic literature review according to the quality standards recommended by the Cochrane Handbook for Systematic Reviews. Randomized controlled trials comparing outcomes of deep neuromuscular blockade and moderate neuromuscular blockade among adults undergoing laparoscopic surgeries were included. A random-effects model was used to conduct pair-wise meta-analyses. RESULTS:The systematic literature review included 15 studies-only 13 were analyzable in the meta-analysis and none were judged to be at high risk of bias. Compared with moderate neuromuscular blockade, deep neuromuscular blockade was associated with improved surgical field of vision and higher vision quality scores. Also, deep neuromuscular blockade was associated with a reduction in the post-operative pain scores in the post-anesthesia care unit compared with moderate neuromuscular blockade, and there was no need for an increase in intra-abdominal pressure during the surgical procedures. There were minor savings on resource utilization, but no differences were seen in recovery in the post-anesthesia care unit or overall length of hospital stay with deep neuromuscular blockade. CONCLUSIONS:Deep neuromuscular blockade may aid the patient and physician surgical experience by improving certain patient outcomes, such as post-operative pain and improved surgical ratings, compared with moderate neuromuscular blockade. Heterogeneity in the pooled estimates suggests the need for better designed randomized controlled trials.

Project description:Neuromuscular blocking agents (NMBAs) are commonly used in experimental laparoscopy in swine undergoing carbon dioxide pneumoperitoneum. Hypercapnia may be present and may prolong NMBAs' pharmacologic activity. The aim of this study is to evaluate the effect of permissive hypercapnia on the neuromuscular blockade of atracurium in swine. Six Large White swine weighing 30.5 ± 1.6 kg were sedated with intramuscular ketamine and medetomidine, after which anaesthesia was induced with propofol and maintained with sevoflurane. Atracurium 0.4 mg/kg was administered intravenously and the neuromuscular block monitored by acceleromyography during normocapnic and hypercapnic conditions (PaCO2 range 35-45 mmHg and 60-70 mmHg, respectively). Onset time and time to reach a train of four ratio (TOFR) of 0.7 and 0.9 were recorded. Cardiorespiratory parameters, electrolytes and acid-base status were measured under both conditions. Onset time was similar between the two conditions. Time to reach a TOFR of 0.7 and 0.9 (duration of the neuromuscular block) was longer in hypercapnic compared to normocapnic animals being 1325 ± 300 vs 855 ±111 (p = 0.002) and 1823 ± 434 vs 1218 ± 210 seconds (p = 0.005), respectively. Three hypercapnic swine had a TOF count of 2 and 1 instead of a count of 4 with fade. Permissive hypercapnia was associated with a decrease in pH from 7.444 ± 0.039 to 7.257 ± 0.025 (p < 0.001). No differences were observed for heart rate, end-tidal concentration of sevoflurane, body temperature and arterial haemoglobin saturation. Nonetheless, hypercapnic swine had a statistically significant increase in mean arterial pressure (p = 0.020) and plasma potassium concentration (p = 0.003). The values of PaCO2 achieved during hypercapnia were well tolerated in swine undergoing CO2 pneumoperitoneum for laparoscopy. Permissive hypercapnia increased the duration of the atracurium effect and caused an increase in the intensity of the neuromuscular block in few swine.

Project description:IntroductionThe management of neuromuscular blockade (NMB) has evolved over time and remains a critical component of general anesthesia. However, NMB use varies by patient and procedural characteristics, clinical practices, protocols, and drug access. National utilization patterns are unknown. We describe changes in NMB and NMB reversal agent administration in surgical inpatients since the US introduction of sugammadex in December 2015.MethodsIn a retrospective observational study of inpatients involving NMB with rocuronium or vecuronium in the Premier Healthcare Database, we estimate associations between factors related to choice of (1) active NMB reversal versus spontaneous recovery and (2) sugammadex versus neostigmine as the reversal agent.ResultsAmong 4.3 million adult inpatient encounters involving rocuronium or vecuronium, the most widely administered NMB agent was rocuronium alone (86%). Over time, gradual declines in both neostigmine use and spontaneous reversal were observed (64% and 36% in 2014 to 38% and 28%, respectively in the first half of 2019). Several factors were independently associated with use of active versus spontaneous NMB recovery including years since 2016, patient (age, race, comorbidities), and procedure (admission and surgery type) characteristics. Among those actively reversed, these and other factors were independently associated with choice of reversal agent administered, including size and teaching affiliation of hospital. While both impacted choices in treatment, the direction and magnitude of effect of patient comorbidities and procedure type varied in their impact on choice of mode (pharmacologic vs. spontaneous) and agent (neostigmine vs. sugammadex) of NMB reversal independent of other factors and each other. Sites which adopted sugammadex earlier were more likely to choose sugammadex over neostigmine compared with later adopters independent of other factors.ConclusionsAmong US adult inpatients administered NMBs, we observed complex relationships between patient, site, procedural characteristics, and NMB management choices as NMBA choice and active reversal options among inpatient cases changed over time.
