Abstract
OBJECTIVE To compare the effectiveness of low intra-abdominal pressure (IAP) facilitated by deep neuromuscular block (NMB) to standard practice in improving the quality of recovery, preserving immune function, and enhancing parietal perfusion during robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS In this blinded, randomised controlled trial, 96 patients were randomised to the experimental group with low IAP (8 mmHg) facilitated by deep NMB (post-tetanic count 1-2) or the control group with standard IAP (14 mmHg) and moderate NMB (train-of-four 1-2). Recovery was measured using the 40-item Quality of Recovery questionnaire and 36-item Short-Form Health survey. Immune function was evaluated by plasma damage-associated molecular patterns, cytokines, and ex vivo lipopolysaccharide-stimulated cytokine production. Parietal peritoneum perfusion was measured by analysing the recordings of indocyanine-green injection. RESULTS Quality of recovery was not superior in the experimental group (n = 46) compared to the control group (n = 50). All clinical outcomes, including pain scores, postoperative nausea and vomiting, and hospital stay were similar. There were no significant differences in postoperative plasma concentrations of damage-associated molecular patterns, cytokines, and ex vivo cytokine production capacity. The use of low IAP resulted in better parietal peritoneum perfusion. CONCLUSION Despite better perfusion of the parietal peritoneum, low IAP facilitated by deep NMB did not improve the quality of recovery or preserve immune function compared to standard practice in patients undergoing RARP.

Abstract
BACKGROUND Laparoscopic surgery is the preferred option for many procedures. To properly perform laparoscopic surgery, it is essential that sudden movements and abdominal contractions in patients are prevented, as it limits the surgeon's view. There has been a growing interest in the potential beneficial effect of deep neuromuscular blockade (NMB) in laparoscopic surgery. Deep NMB improves the surgical field by preventing abdominal contractions, and it is thought to decrease postoperative pain. However, it is uncertain if deep NMB improves intraoperative safety and thereby improves clinical outcomes. OBJECTIVES To evaluate the benefits and harms of deep neuromuscular blockade versus no, shallow, or moderate neuromuscular blockade during laparoscopic intra- or transperitoneal procedures in adults. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was 31 July 2023. SELECTION CRITERIA We included randomised clinical trials (irrespective of language, blinding, or publication status) in adults undergoing laparoscopic intra- or transperitoneal procedures comparing deep NMB to moderate, shallow, or no NMB. We excluded trials that did not report any of the primary or secondary outcomes of our review. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were 1. all-cause mortality, 2. health-related quality of life, and 3. proportion of participants with serious adverse events. Our secondary outcomes were 4. proportion of participants with non-serious adverse events, 5. readmissions within three months, 6. short-term pain scores, 7. measurements of postoperative recovery, and 8. operating time. We used GRADE to assess the certainty of evidence for each outcome. MAIN RESULTS We included 42 randomised clinical trials with 3898 participants. Most trials included participants undergoing intraperitoneal oncological resection surgery. We present the Peto fixed-effect model for most dichotomous outcomes as only sparse events were reported. Comparison 1: deep versus moderate NMB Thirty-eight trials compared deep versus moderate NMB. Deep NMB may have no effect on mortality, but the evidence is very uncertain (Peto odds ratio (OR) 7.22, 95% confidence interval (CI) 0.45 to 115.43; 12 trials, 1390 participants; very low-certainty evidence). Deep NMB likely results in little to no difference in health-related quality of life up to four days postoperative (mean difference (MD) 4.53 favouring deep NMB on the Quality of Recovery-40 score, 95% CI 0.96 to 8.09; 5 trials, 440 participants; moderate-certainty evidence; mean difference lower than the mean clinically important difference of 10 points). The evidence is very uncertain about the effect of deep NMB on intraoperatively serious adverse events (deep NMB 38/1150 versus moderate NMB 38/1076; Peto OR 0.95, 95% CI 0.59 to 1.52; 21 trials, 2231 participants; very low-certainty evidence), short-term serious adverse events (up to 60 days) (deep NMB 37/912 versus moderate NMB 42/852; Peto OR 0.90, 95% CI 0.56 to 1.42; 16 trials, 1764 participants; very low-certainty evidence), and short-term non-serious adverse events (Peto OR 0.94, 95% CI 0.65 to 1.35; 11 trials, 1232 participants; very low-certainty evidence). Deep NMB likely does not alter the duration of surgery (MD -0.51 minutes, 95% CI -3.35 to 2.32; 34 trials, 3143 participants; moderate-certainty evidence). The evidence is uncertain if deep NMB alters the length of hospital stay (MD -0.22 days, 95% CI -0.49 to 0.06; 19 trials, 2084 participants; low-certainty evidence) or pain scores one hour after surgery (MD -0.31 points on the numeric rating scale, 95% CI -0.59 to -0.03; 22 trials, 1823 participants; very low-certainty evidence; mean clinically important difference 1 point) and 24 hours after surgery (MD -0.60 points on the numeric rating scale, 95% CI -1.05 to -0.15; 16 trials, 1404 participants; very low-certainty evidence; mean clinically important difference 1 point). Comparison 2: deep versus shallow NMB Three trials compared deep versus shallow NMB. The trials did not report on mortality and health-related quality of life. The evidence is very uncertain about the effect of deep NMB compared to shallow NMB on the proportion of serious adverse events (RR 1.66, 95% CI 0.50 to 5.57; 2 trials, 158 participants; very low-certainty evidence). Comparison 3: deep versus no NMB One trial compared deep versus no NMB. There was no mortality in this trial, and health-related quality of life was not reported. The proportion of serious adverse events was 0/25 in the deep NMB group and 1/25 in the no NMB group. AUTHORS' CONCLUSIONS There was insufficient evidence to draw conclusions about the effects of deep NMB compared to moderate NMB on all-cause mortality and serious adverse events. Deep NMB likely results in little to no difference in health-related quality of life and duration of surgery compared to moderate NMB, and it may have no effect on the length of hospital stay. Due to the very low-certainty evidence, we do not know what the effect is of deep NMB on non-serious adverse events, pain scores, or readmission rates. Randomised clinical trials with adequate reporting of all adverse events would reduce the current uncertainties. Due to the low number of identified trials and the very low certainty of evidence, we do not know what the effect of deep NMB on serious adverse events is compared to shallow NMB and no NMB. We found no trials evaluating mortality and health-related quality of life.

Abstract
BACKGROUND Neuromuscular block (NMB) is routinely used in paediatric and adult anaesthesia to facilitate endotracheal intubation and optimise surgical conditions. However, there are limited data regarding NMB and optimising the conditions for laparoscopic surgery in neonates and small infants. OBJECTIVE The goal of this study was to determine the effect of NMB on the conditions for laparoscopic surgery in neonates and small infants. DESIGN A randomised controlled trial. SETTING Single-centre Children's Hospital, conducted from November 2021 to December 2022. PATIENTS One hundred and two ASA I-II neonates and small infants aged up to 60 weeks postmenstrual age who were scheduled to undergo an elective laparoscopic Ladd's procedure were included in the study. INTERVENTIONS Patients were randomised into three groups: no NMB group, shallow NMB group and moderate NMB group. Each group was given different doses of rocuronium to achieve the target depth of NMB. MAIN OUTCOME MEASURES The primary outcome was the quality of the surgical conditions evaluated with the Leiden-Surgical Rating Scale (L-SRS) by a blinded surgeon. Secondary outcomes included tracheal intubating conditions and adverse events. RESULTS The percentage of L-SRS scores of 4 or 5 was similar among the three groups at all the assessment times ( P > 0.05 for each time interval). The distribution of L-SRS scores was also similar among the three groups. There were no significant differences in operating condition scores between the groups at any time interval ( P > 0.05 for each time interval). The incidence of adverse events during anaesthesia induction was significantly higher in the no NMB group (51.4%) than in the other two groups (13.6% and 14.7%) (adjusted P = 0.012 and adjusted P = 0.003). In particular, clinically unacceptable intubation conditions occurred in 12 patients (34.3%) in the no NMB group, significantly more than in the shallow NMB group (6.1%, adjusted P = 0.012) and moderate NMB group (2.9%, adjusted P = 0.003). There was no statistically significant difference in the incidence of adverse events in the PACU among the three groups ( P = 0.103). CONCLUSIONS The depth of NMB was not associated with superior surgical conditions during laparoscopic surgery, but it was associated with a reduction in adverse events during induction and maintenance of anaesthesia in neonates and small infants.

Abstract
BACKGROUND Demographics of patients undergoing major abdominal surgery are changing. External validity of relevant RCTs may be limited by participants not resembling patients encountered in clinical practice. We aimed to characterise differences in age, weight, BMI, and ASA grade between participants in perioperative trials in major abdominal surgery and patients in a reference real-world clinical practice sample. The secondary aim was to investigate whether time since trial publication was associated with increasing mismatch between these groups. METHODS MEDLINE and Embase were searched for multicentre RCTs from inception to September 2022. Studies of perioperative interventions in adults were included. Studies that limited enrolment based on age, weight, BMI, or ASA status were excluded. We compared trial cohort age, weight, BMI, and ASA distribution to those of patients undergoing major abdominal surgery at our tertiary referral hospital during September 2021 to September 2022. We used a local, single-institution reference sample to reflect the reality of clinical practice (i.e. patients treated by a clinician in their own hospital, rather than averaged nationally). Mismatch was defined using comparison of summary characteristics and ad hoc criteria based on differences relevant to predicted mortality risk after surgery. RESULTS One-hundred and six trials (44,499 participants) were compared to a reference cohort of 2792 clinical practice patients. Trials were published a median (IQR [range]) 13.4 (5-20 [0-35]) years ago. A total of 94.3% of trials were mismatched on at least one characteristic (age, weight, BMI, ASA). Recruitment of ASA 3 + participants in trials increased over time, and recruitment of ASA 1 participants decreased over time (Spearman's Rho 0.58 and - 0.44, respectively). CONCLUSIONS Patients encountered in our current local clinical practice are significantly different from those in our defined set of perioperative RCTs. Older trials recruit more low-risk than high-risk participants-trials may thus 'expire' over time. These trials may not be generalisable to current patients undergoing major abdominal surgery, and meta-analyses or guidelines incorporating these trials may therefore be similarly non-applicable. Comparison to local, rather than national cohorts, is important for meaningful on-the-ground evidence-based decision-making.

Abstract
Background Few studies have examined the effect of epidural block on surgical conditions during pediatric subumbilical laparoscopic surgery involving a supraglottic airway (SGA). This study investigated the surgical condition scores for such procedures in cases where neuromuscular block, epidural block, or neither was used. Methods A total of 150 patients aged 3-12 years undergoing laparoscopic orchiopexy with a ProSeal SGA device were randomly allocated to one of three groups: the control group (did not receive neuromuscular block and epidural block), the NMB group [received a neuromuscular block (train-of-four 1-2 twitches) using rocuronium], or the EDB group (received an epidural block using ropivacaine). The primary outcome was the quality of surgical conditions evaluated with the Leiden-Surgical Rating Scale by the blinded surgeon. The secondary outcome measures included intraoperative hemodynamic data (including mean arterial pressure and heart rate), the SGA device removal time, the PACU discharge time, the pain score in the PACU and intraoperative adverse events (including bradycardia, hypotension, peak airway pressure > 20 cmH2O, and poor or extremely poor surgical conditions occurred during the operation). Statistical analysis was performed with one-way analysis of variance, the Kruskal-Wallis test, the chi-square test or Fisher's exact test. Bonferroni corrections for multiple comparisons were made for primary and secondary outcomes. Results Surgical condition scores were significantly higher in the NMB and EDB groups than in the control group (median difference: 0.8; 95% confidence interval [CI], 0.5-1.0; p < 0.0001; and median difference: 0.7; 95% CI, 0.5-0.8; p < 0.0001, respectively). Blood pressure and heart rate were significantly lower in the EDB group than in the other two groups (p < 0.0001 and p = 0.004). Patients in the EDB group had significantly lower pain scores during PACU than those in the other two groups (p < 0.0001). The sufentanil dose was lower in the EDB group than in the other two groups (p = 0.001). Conclusion Epidural block can improve surgical conditions during pediatric subumbilical laparoscopic surgery involving a SGA to a degree comparable to that with moderate neuromuscular block.

Abstract
Recent data indicated a high incidence of inappropriate management of neuromuscular block, with a high rate of residual paralysis and relaxant-associated postoperative complications. These data are alarming in that the available neuromuscular monitoring, as well as myorelaxants and their antagonists basically allow well tolerated management of neuromuscular blockade. In this first European Society of Anaesthesiology and Intensive Care (ESAIC) guideline on peri-operative management of neuromuscular block, we aim to present aggregated and evidence-based recommendations to assist clinicians provide best medical care and ensure patient safety. We identified three main clinical questions: Are myorelaxants necessary to facilitate tracheal intubation in adults? Does the intensity of neuromuscular blockade influence a patient's outcome in abdominal surgery? What are the strategies for the diagnosis and treatment of residual paralysis? On the basis of this, PICO (patient, intervention, comparator, outcome) questions were derived that guided a structured literature search. A stepwise approach was used to reduce the number of trials of the initial research ( n = 24 000) to the finally relevant clinical studies ( n = 88). GRADE methodology (Grading of Recommendations, Assessment, Development and Evaluation) was used for formulating the recommendations based on the findings of the included studies in conjunction with their methodological quality. A two-step Delphi process was used to determine the agreement of the panel members with the recommendations: R1 We recommend using a muscle relaxant to facilitate tracheal intubation (1A). R2 We recommend the use of muscle relaxants to reduce pharyngeal and/or laryngeal injury following endotracheal intubation (1C). R3 We recommend the use of a fast-acting muscle relaxant for rapid sequence induction intubation (RSII) such as succinylcholine 1 mg kg -1 or rocuronium 0.9 to 1.2 mg kg -1 (1B). R4 We recommend deepening neuromuscular blockade if surgical conditions need to be improved (1B). R5 There is insufficient evidence to recommend deep neuromuscular blockade in general to reduce postoperative pain or decrease the incidence of peri-operative complications. (2C). R6 We recommend the use of ulnar nerve stimulation and quantitative neuromuscular monitoring at the adductor pollicis muscle to exclude residual paralysis (1B). R7 We recommend using sugammadex to antagonise deep, moderate and shallow neuromuscular blockade induced by aminosteroidal agents (rocuronium, vecuronium) (1A). R8 We recommend advanced spontaneous recovery (i.e. TOF ratio >0.2) before starting neostigmine-based reversal and to continue quantitative monitoring of neuromuscular blockade until a TOF ratio of more than 0.9 has been attained.

Abstract
Deep neuromuscular blockade provides better surgical workspace conditions in laparoscopic surgery, but it is still not clear whether it improves perioperative outcomes, not to mention its role in other types of surgeries. We performed this systematic review and meta-analysis of randomized controlled trials to investigate whether deep neuromuscular blockade versus other more superficial levels of neuromuscular blockade provides improved perioperative outcomes in adult patients in all types of surgeries. Medline, Embase, Cochrane Central Register of Controlled Trials, and Google Scholar were searched from inception to June 25, 2022. Forty studies (3271 participants) were included. Deep neuromuscular blockade was associated with an increased rate of acceptable surgical condition (relative risk [RR]: 1.19, 95% confidence interval [CI]: [1.11, 1.27]), increased surgical condition score (MD: 0.52, 95% CI: [0.37, 0.67]), decreased rate of intraoperative movement (RR: 0.19, 95% CI: [0.10, 0.33]), fewer additional measures to improve the surgical condition (RR: 0.63, 95% CI: [0.43, 0.94]), and decreased pain score at 24 h (MD: -0.42, 95% CI: [-0.74, -0.10]). There was no significant difference in the intraoperative blood loss (MD: -22.80, 95% CI: [-48.83, 3.24]), duration of surgery (MD: -0.05, 95% CI: [-2.05, 1.95]), pain score at 48 h (MD: -0.49, 95% CI: [-1.03, 0.05]), or length of stay (MD: -0.05, 95% CI: [-0.19, 0.08]). These indicate that deep neuromuscular blockade improves surgical conditions and prevents intraoperative movement, and there is no sufficient evidence that deep neuromuscular blockade is associated with intraoperative blood loss, duration of surgery, complications, postoperative pain, and length of stay. More high-quality randomized controlled trials are needed, and more attention should be given to complications and the physiological mechanism behind deep neuromuscular blockade and postoperative outcomes.

Abstract
In laparoscopic surgery the abdominal cavity is insufflated with pressurized carbon dioxide gas to create workspace. This pressure is exerted through the diaphragm onto the lungs, competing with ventilation and hampering it. In clinical practice the difficulty of optimizing this balance can lead to the application of harmfully high pressures. This study set out to create a research platform for the investigation of the complex interaction between insufflation and ventilation in an animal model. The research platform was constructed to incorporate insufflation, ventilation and relevant hemodynamic monitoring devices, controlling insufflation and ventilation from a central computer. The core of the applied methodology is the fixation of physiological parameters by applying closed-loop control of specific ventilation parameters. For accurate volumetric measurements the research platform can be used in a CT scanner. An algorithm was designed to keep blood carbon dioxide and oxygen values stable, minimizing the effect of fluctuations on vascular tone and hemodynamics. This design allowed stepwise adjustment of insufflation pressure to measure the effects on ventilation and circulation. A pilot experiment in a porcine model demonstrated adequate platform performance. The developed research platform and protocol automation have the potential to increase translatability and repeatability of animal experiments on the biomechanical interactions between insufflation and ventilation.

Abstract
Most urological interventions are now performed with minimally invasive surgery techniques such as laparoscopic surgery. Combining ERAS protocols with minimally invasive surgery techniques may be the best option to reduce hospital length-of-stay and post-operative complications. We designed this study to test the hypothesis that using low intra-abdominal pressures (IAP) during laparoscopy may reduce post-operative complications, especially those related to reduced intra-operative splanchnic perfusion or increased splanchnic congestion. We applied a complete neuromuscular blockade (NMB) to maintain an optimal space and surgical view. We compared 115 patients treated with standard IAP and moderate NMB with 148 patients treated with low IAP and complete NMB undergoing major urologic surgery. Low IAP in combination with complete NMB was associated with fewer total post-operative complications than standard IAP with moderate NMB (22.3% vs. 41.2%, p < 0.001), with a reduction in all medical post-operative complications (17 vs. 34, p < 0.001). The post-operative complications mostly reduced were acute kidney injury (15.5% vs. 30.4%, p = 0.004), anemia (6.8% vs. 16.5%, p = 0.049) and reoperation (2% vs. 7.8%, p = 0.035). The intra-operative management of laparoscopic interventions for major urologic surgeries with low IAP and complete NMB is feasible without hindering surgical conditions and might reduce most medical post-operative complications.

[PMID: 35864355 PMCID: PMC9402757 DOI: 10.1007/s00464-022-09406-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Accepted: 06/19/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND Abdominal compliance describes the ease of expansion of the abdominal cavity. Several studies highlighted the importance of monitoring abdominal compliance (Cab) during the creation of laparoscopic workspace to individualize the insufflation pressure. The lack of validated clinical monitoring tools for abdominal compliance prevents accurate tailoring of insufflation pressure. Oscillometry, also known as the forced oscillation technique (FOT), is currently used to measure respiratory mechanics and has the potential to be adapted for monitoring abdominal compliance. This study aimed to define, develop and evaluate a novel approach which can monitor abdominal compliance during laparoscopy using endoscopic oscillometry. MATERIALS AND METHODS Endoscopic oscillometry was evaluated in a porcine model for laparoscopy. A custom-built insufflator was developed for applying an oscillatory pressure signal superimposed onto a mean intra-abdominal pressure. This insufflator was used to measure the abdominal compliance at insufflation pressures ranging from 5 to 20 hPa (3.75 to 15 mmHg). The measurements were compared to the static abdominal compliance, which was measured simultaneously with computed tomography imaging. RESULTS Endoscopic oscillometry recordings and CT images were obtained in 10 subjects, resulting in 76 measurement pairs for analysis. The measured dynamic Cab ranged between 0.0216 and 0.261 L/hPa while the static Cab based on the CT imaging ranged between 0.0318 and 0.364 L/hPa. The correlation showed a polynomial relation and the adjusted R-squared was 97.1%. CONCLUSIONS Endoscopic oscillometry can be used to monitor changes in abdominal compliance during laparoscopic surgery, which was demonstrated in this study with a comparison with CT imaging in a porcine laparoscopy model. Use of this technology to personalize the insufflation pressure could reduce the risk of applying excessive pressure and limit the drawbacks of insufflation.

Abstract
Background Deep neuromuscular blockade may be beneficial on surgical space conditions during laparoscopic surgery. The effects of moderate neuromuscular blockade combined with transverse abdominal plane block (TAPB) on surgical space conditions during laparoscopic surgery have not been described. This work investigated whether the above combination is associated with similar surgical space conditions to those of deep neuromuscular blockade. Methods Eighty patients undergoing elective laparoscopic surgery for colorectal cancer were randomly divided into two groups. The intervention group was treated with moderate neuromuscular blockade (train-of-four (TOF) count between 1 and 3) combined with TAPB (M group), while the control group was treated with deep neuromuscular blockade (D group), with a TOF count of 0 and a post-tetanic count (PTC) ≥1. Both groups received the same anesthesia management. The distance between the sacral promontory and the umbilical skin during the operation was compared between the two groups. The surgeon scored the surgical space conditions according to a five-point ordinal scale. Patients’ pain scores were evaluated 8 h after the operation. Results The distance from the sacral promontory to the umbilical skin after pneumoperitoneum was similar between the D group and M group (16.03 ± 2.17 cm versus 16.37 ± 2.78 cm; P = 0.544). The 95% confidence intervals of the difference in the distance from the sacral promontory to the umbilical skin between the two groups were − 1.45–0.77 cm. According to the preset non-inferior standard of 1.5 cm, (− 1.45, ∞) completely fell within (− 1.50, ∞), and the non-inferior effect test was qualified. No significant difference was found in the surgical rating score between the two groups. The dosage of rocuronium in the group D was significantly higher than that in the group M (P < 0.01). The M group had significantly lower pain scores than the D group 8 h after the operation (P < 0.05). Conclusions Moderate neuromuscular blockade combined with TAPB applied to laparoscopic colorectal cancer surgery can provide surgical space conditions similar to those of deep neuromuscular blockade. In addition, it reduces the use of muscle relaxants, relieves postoperative pain within 4 h after operation, and shorten the extubation time and stay in PACU when neostigmine was used as muscle relaxant antagonist.

Abstract
Background: To investigate whether deep neuromuscular blockade (NMB) improves surgical conditions and postoperative pain compared to moderate block, in patients undergoing gynecologic laparoscopic surgery. Methods: A single blind, randomized, controlled trial was undertaken with laparoscopic gynecologic surgical patients, who were randomly assigned to one of the following two groups: patients in the first group received deep NMB (PTC 0-1) and in the other, moderate NMB (TOF 0-1). Primary outcomes included assessing the surgical conditions using a four-grade scale, ranging from 0 (extremely poor) to 3 (optimal), and patients’ postoperative pain was evaluated with a five-grade Likert scale and the analgesic consumption. Results: 144 patients were analyzed as follows: 73 patients received deep NMB and 71 moderate NMB. Mean surgical field scores were comparable between the two groups (2.44 for moderate vs. 2.68 for deep NMB). Regarding postoperative pain scores, the patients in the deep NMB experienced significantly less pain than in the group of moderate NMB (0.79 vs. 1.58, p < 0.001). Moreover, when the consumption of analgesic drugs was compared, the moderate NMB group needed more extra opioid analgesia than the deep NMB group (18.3% vs. 4.1%, p = 0.007). From the secondary endpoints, an interesting finding of the study was that patients on deep NMB had significantly fewer incidents of subcutaneous emphysema. Conclusions: Our data show that, during the performance of gynecologic laparoscopic surgery, deep NMB offers no advantage of operating filed conditions compared with moderate NMB. Patients may benefit from the deep block as it may reduce postoperative pain.

Abstract
Background This is the second updated Enhanced Recovery After Surgery (ERAS®) Society guideline, presenting a consensus for optimal perioperative care in bariatric surgery and providing recommendations for each ERAS item within the ERAS® protocol. Methods A principal literature search was performed utilizing the Pubmed, EMBASE, Cochrane databases and ClinicalTrials.gov through December 2020, with particular attention paid to meta-analyses, randomized controlled trials and large prospective cohort studies. Selected studies were examined, reviewed and graded according to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. After critical appraisal of these studies, the group of authors reached consensus regarding recommendations. Results The quality of evidence for many ERAS interventions remains relatively low in a bariatric setting and evidence-based practices may need to be extrapolated from other surgeries. Conclusion A comprehensive, updated evidence-based consensus was reached and is presented in this review by the ERAS® Society.

Deep neuromuscular block reduces the incidence of intra-operative complications during laparoscopic donor nephrectomy: a pooled analysis of randomized controlled trials. Perioper Med (Lond) 2021; 10:56.

Abstract
Study objective To assess whether different intensities of intra-abdominal pressure and deep neuromuscular blockade influence the risk of intra-operative surgical complications during laparoscopic donor nephrectomy. Design A pooled analysis of ten previously performed prospective randomized controlled trials. Setting Laparoscopic donor nephrectomy performed in four academic hospitals in the Netherlands: Radboudumc, Leiden UMC, Erasmus MC Rotterdam, and Amsterdam UMC. Patients Five hundred fifty-six patients undergoing a transperitoneal, fully laparoscopic donor nephrectomy enrolled in ten prospective, randomized controlled trials conducted in the Netherlands from 2001 to 2017. Interventions Moderate (tetanic count of four > 1) versus deep (post-tetanic count 1–5) neuromuscular blockade and standard (≥10 mmHg) versus low (<10 mmHg) intra-abdominal pressure. Measurements The primary endpoint is the number of intra-operative surgical complications defined as any deviation from the ideal intra-operative course occurring between skin incision and closure with five severity grades, according to ClassIntra. Multiple logistic regression analyses were used to identify predictors of intra- and postoperative complications. Main results In 53/556 (9.5%) patients, an intra-operative complication with ClassIntra grade ≥ 2 occurred. Multiple logistic regression analyses showed standard intra-abdominal pressure (OR 0.318, 95% CI 0.118–0.862; p = 0.024) as a predictor of less intra-operative complications and moderate neuromuscular blockade (OR 3.518, 95% CI 1.244–9.948; p = 0.018) as a predictor of more intra-operative complications. Postoperative complications occurred in 31/556 (6.8%), without significant predictors in multiple logistic regression analyses. Conclusions Our data indicate that the use of deep neuromuscular blockade could increase safety during laparoscopic donor nephrectomy. Future randomized clinical trials should be performed to confirm this and to pursue whether it also applies to other types of laparoscopic surgery.

Deep Neuromuscular Blockade Combined with Low Pneumoperitoneum Pressure for Nociceptive Recovery After Major Laparoscopic Gastrointestinal Surgery: Study Protocol for a Randomized Controlled Trial. J Pain Res 2021; 14:3573-3581.

Abstract
Purpose Patients undergoing major laparoscopic surgery often experience significant pain and postoperative nausea and vomiting (PONV). Deep neuromuscular block (NMB) improves surgical conditions and facilitates the application of low intra-abdominal pressure (IAP), which may be beneficial for these patients. This study is designed to determine the effects of deep NMB combined with low IAP, as compared to moderate NMB combined with standard IAP, on patients' nociceptive recovery after major laparoscopic gastrointestinal surgery. Study Design and Methods This single-center randomized controlled trial will include 220 patients scheduled for major laparoscopic gastrointestinal surgery (lasts for ≥ 90 minutes). Patients will be randomly assigned, with a 1:1 ratio, into a deep NMB + low IAP group (train of four = 0, post-tetanic count = 1-3, IAP = 8 mmHg) and a moderate NMB + standard IAP group (train of four = 1-3, IAP = 12 mmHg). If the surgical workspace is inadequate, the surgeons can request a step increase of 1 mmHg in IAP during 3-min intervals. The upper limit of IAP will be set at 15 mmHg. Postoperative recovery will be assessed using the postoperative quality recovery scale (PQRS). The primary outcome of this trial is the PQRS nociceptive recovery (including pain and PONV) at postoperative day (POD) 1. The secondary outcomes include recovery in other PQRS domains at POD 1, and recovery in all PQRS domains in a post-anesthesia care unit, at POD 3 in the surgical wards, at hospital discharge, and at postoperative 30 days. For the sample size estimation, 110 patients in each group (220 in total) would be needed to detect an absolute increase rate of 20% in the PQRS nociceptive domain in the deep NMB + low IAP group at POD 1. Discussion This study investigates the effects of deep NMB combined with low IAP on postoperative PQRS nociceptive recovery in patients undergoing major laparoscopic gastrointestinal surgery. We expect that this deep NMB + low IAP strategy would improve postoperative pain and PONV following major laparoscopic gastrointestinal surgery.

Abstract
Background Muscle relaxants are routinely used during anesthesia to facilitate endotracheal intubation and to optimize surgical conditions. However, controversy remains about the required depth of neuromuscular block (NMB) needed for optimal surgical working conditions and how this relates to other outcomes. For instance, a deep neuromuscular block yields superior surgical working conditions compared to a standard NMB in laparoscopic surgery, however, a robust association to other (safety) outcomes has not yet been established. Methods Trial design: an international multicenter randomized controlled double-blind strategy trial. Trial population: 922 patients planned for elective, laparoscopic or robotic, abdominal surgery. Intervention: Patients will be randomized to a deep NMB (post-tetanic count 1–2 twitches) or standard care (single-dose muscle relaxant administration at induction and repeated only if warranted by surgical team). Main trial endpoints: Primary endpoint is the difference in incidence of intraoperative adverse events during laparoscopic surgery graded according to ClassIntra® classification (i.e., ClassIntra® grade ≥ 2) between both groups. Secondary endpoints include the surgical working conditions, 30-day postoperative complications, and patients’ quality of recovery. Discussion This trial was designed to analyze the effect of deep neuromuscular block compared to standard neuromuscular block on intra- and postoperative adverse events in patients undergoing laparoscopic surgery.

Richebé P, Bousette N, Fortier LP. A narrative review on the potential benefits and limitations of deep neuromuscular blockade. Anaesth Crit Care Pain Med 2021; 40:100915.

Abstract
BACKGROUND Neuromuscular blockade was shown to improve surgical conditions. However, the risk of residual neuromuscular blockade upon extubation prevents anaesthesiologists from maintaining complete paralysis. For this reason, deep NMB is still underused in anaesthesia. This review focused on answering six questions revolving around the use of deep NMB versus moderate NMB. METHODS This was a non-exhaustive narrative review based on 6 selected relevant questions: does deep NMB 1) improve surgical conditions? 2) reduce surgical complications? 3) facilitate a reduction in intraoperative pneumoperitoneum pressure (PnP)? 4) does a reduction in intraoperative PnP impact clinical outcomes? 5) does the combination of deep NMB and lower PnP improve respiratory parameters? 6) improve OR efficiency or readmission rates? RESULTS This review highlights some of the key studies that have demonstrated potential benefits of deep NMB, but it also included reports showing no benefit, highlighting that the evidence is not unequivocal. Deep NMB does in fact improve surgical conditions, but whether this improvement translates into improved clinical outcomes is far from concluded. Indeed, there is an increased risk or residual curarisation, especially if patients are not monitored and reversed appropriately. The most important benefit of deep NMB may be the prevention of unacceptable surgical working conditions. The other potential major benefits are the reduction in PnP and reduction in pain. Deep NMB must be used with appropriate monitoring. CONCLUSION Deep NMB was associated with an improvement in surgical conditions, reduction in PnP, pain, and complications; but further research is needed to definitively prove this relationship.

Abstract
BACKGROUND Anesthesia with deep neuromuscular block for laparoscopic surgery may result in less postoperative pain with lower intra-abdominal pressure. However, results in the existing literature are controversial. OBJECTIVE The study aimed to evaluate the effect of deep neuromuscular block on postoperative pain at rest and during coughing after laparoscopic colorectal surgery. DESIGN The design is a parallel-group, randomized clinical trial. SETTINGS The study was conducted at a tertiary care center. PATIENTS Patients undergoing laparoscopic resection of colorectal tumors were included. INTERVENTIONS Patients were randomly assigned to either a deep (posttetanic count 1 to 2) or moderate (train-of-four 1 to 2) neuromuscular group. MAIN OUTCOME MEASURES The coprimary efficacy outcomes were numeric rating scale scores of the postoperative pain at rest and during coughing after surgery. RESULTS Pain was lower in the deep neuromuscular block group at rest and during coughing at 1, 6, 24, and 48 hours after surgery (median difference of 2 points and 1 point at 1 h; p < 0.001 at each time point). The deep neuromuscular block group displayed a significantly lower number of bolus attempts by the patient (4 in the deep group vs 9 in the moderate group; p < 0.001) and boluses delivered (4 in the deep group vs 9 in the moderate group; p < 0.001) on postoperative day 1. The number of rescue analgesics was lower in the deep group on postoperative day 2 (p < 0.001). The deep neuromuscular block group showed a lower frequency of postoperative nausea and vomiting (p = 0.02) and lower intraoperative intra-abdominal pressure (p < 0.001). LIMITATIONS This was a single-center study. CONCLUSIONS Deep neuromuscular block resulted in better pain relief and lower opioid consumption and use of rescue analgesics after laparoscopic colorectal surgery. Deep neuromuscular block was associated with less postoperative nausea and vomiting and facilitated the use of lower intra-abdominal pressure in laparoscopic surgery.

Deep neuromuscular block does not improve surgical conditions in patients receiving sevoflurane anaesthesia for laparoscopic renal surgery. Br J Anaesth 2020; 126:377-385. [PMID: 33092803 PMCID: PMC7572301 DOI: 10.1016/j.bja.2020.09.024] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 09/18/2020] [Accepted: 09/18/2020] [Indexed: 02/07/2023] Open
Abstract
Background Deep neuromuscular block is associated with improved working conditions during laparoscopic surgery when propofol is used as a general anaesthetic. However, whether deep neuromuscular block yields similar beneficial effects when anaesthesia is maintained using volatile inhalation anaesthesia has not been systematically investigated. Volatile anaesthetics, as opposed to intravenous agents, potentiate muscle relaxation, which potentially reduces the need for deep neuromuscular block to obtain optimal surgical conditions. We examined whether deep neuromuscular block improves surgical conditions over moderate neuromuscular block during sevoflurane anaesthesia. Methods In this single-centre, prospective, randomised, double-blind study, 98 patients scheduled for elective renal surgery were randomised to receive deep (post-tetanic count 1–2 twitches) or a moderate neuromuscular block (train-of-four 1–2 twitches). Anaesthesia was maintained with sevoflurane and titrated to bispectral index values between 40 and 50. Pneumoperitoneum pressure was maintained at 12 mm Hg. The primary outcome was the difference in surgical conditions, scored at 15 min intervals by one of eight blinded surgeons using a 5-point Leiden-Surgical Rating Scale (L-SRS) that scores the quality of the surgical field from extremely poor1 to optimal5. Results Deep neuromuscular block did not improve surgical conditions compared with moderate neuromuscular block: mean (standard deviation) L-SRS 4.8 (0.3) vs 4.8 (0.4), respectively (P=0.94). Secondary outcomes, including unplanned postoperative readmissions and prolonged hospital admission, were not significantly different. Conclusions During sevoflurane anaesthesia, deep neuromuscular block did not improve surgical conditions over moderate neuromuscular block in normal-pressure laparoscopic renal surgery.

Abstract
Background Neuromuscular blockade (NMB) is thought to improve operative conditions during certain procedures. Published descriptions of minimally invasive hip replacement techniques specify the need for “excellent relaxation”, however, the optimal degree of NMB required for such cases has not been studied. We performed a randomized, single-blind study comparing the effect of moderate and deep neuromuscular blockade on surgical conditions and operating time during minimally invasive anterolateral hip replacement. Vecuronium was administered to maintain moderate NMB (train-of-four count of 1-2) or deep NMB (train-of-four count of 0, post-tetanic count of 1-2). Methods In this study, 116 patients were randomized to receive moderate or deep neuromuscular blockade; depth of blockade was monitored using acceleromyography. The primary outcome was the number of requests from the surgeon for additional blockade intraoperatively. Secondary outcomes included operative times and assessment of the operative conditions by the surgeon utilizing the Leiden-Surgical Rating Scale. Results Cases with additional requests for blockade did not differ between the deep and moderate NMB groups (11/58, 19.0% vs 8/58, 13.8%); relative risk, 1.22 (95% CI [confidence interval], 0.70-2.15), p=0.62. Neither time from incision to prosthesis reduction (33.8±1.2 min vs. 32.6 ±1.2 min; difference in geometric mean, 0.96 [95% CI, 0.90-1.04] minutes, p=0.33), nor the surgeon’s assessment of operative conditions (p=0.88), differed between the deep or moderate NMB groups, respectively. Conclusions Deep NMB did not produce significantly improved operative conditions compared with moderate NMB. Routine use of deep NMB during minimally invasive anterolateral hip arthroplasty is not supported by this study.

Abstract
PURPOSE During pneumoperitoneum (PP) for robot-assisted prostatectomy, a deep neuromuscular block (NMB) is necessary. New relaxometry equipment permits maintenance of profound NMB in order to improve patient safety and surgical conditions. METHODS Twenty adult patients undergoing robot-assisted prostatectomy were included. Under automated quantitative relaxometry with the TOFcuffTM device, rocuronium dosing was adapted with the aim to keep NMB at deep levels. The time fractions with intense block (PTC 0), adequately deep block (PTC 1 to 3) and a not sufficiently deep block (PTC > 3) were quantified. RESULTS An optimally deep block (PTC 1-3) was achieved during 110 ± 38 min (50 ± 15%). Intense block was found during 60 ± 45 min (27 ± 18%) of total PP time. Values of PTC > 3 lasted 60 ± 45 min (23 ± 17%). Median PTC always remained between 1 and 3. Inadvertent movements during PP were never encountered, and operation conditions as reported by the surgeons were excellent. CONCLUSION Our technique of controlled profound NMB by repetitive bolus doses achieved its goal in 77% of PP time. Under automated quantitative relaxometry, an optimized rocuronium dosing strategy should be applied to maintain a high level of safety and adequate operation conditions without risking an unnecessary prolongation of NMB into the post-pneumoperitoneum period.

Abstract
Background Patients with diabetes mellitus are at a high risk of developing postoperative acute kidney injury. For patients receiving laparoscopic surgery, standard-pressure pneumoperitoneum (SPP) currently applied in clinical practice also undermines renal perfusion. Several studies have shown that low-pressure pneumoperitoneum (LPP) might reduce pressure-related ischemic renal injury. However, LPP may compromise the view of the surgical field. Previous studies have indicated that deep neuromuscular blockade (NMB) can ameliorate this issue. However, the conclusion is still uncertain. The hypothesis of this study is that the joint use of LPP and deep NMB can reduce perioperative renal injury in diabetic patients undergoing laparoscopic pelvic surgery without impeding the view of the surgical field. Methods This is a double-blinded, randomized controlled trial using a 2 × 2 factorial trial design. A total of 648 diabetes patients scheduled for major laparoscopic pelvic surgeries at Peking Union Medical College Hospital will be randomized into the following four groups: SPP (12–15 mmHg) + deep-NMB (post-tetanic count of 1–2) group, LPP (7–10 mmHg) + deep-NMB group, SPP + moderate-NMB (train-of-four of 1–2) group, and LPP + moderate-NMB group. The primary outcome is serum cystatin C level measured before insufflation, after deflation, 24 h postoperatively, and 72 h postoperatively. The secondary outcomes are serum creatinine level, intraoperative urine output, erythrocytes in urinary sediment, renal tissue oxygen saturation, Leiden’s surgical condition rating scale, surgery duration, and occurrence of bucking or body movement. Discussion This study will provide evidence for the effect of LPP on renal function protection in patients with diabetes undergoing laparoscopic pelvic surgery. The trial can also help us to understand whether deep NMB can improve surgical conditions. Trial registration ClinicalTrials.gov: NCT04259112. Prospectively registered on 5 February 2020.

Abstract
Objective We aimed to investigate the effects of high-dose rocuronium administration on intra-abdominal pressure (IAP) and surgical conditions during anaesthesia induction and laparoscopic cholecystectomy anaesthesia induction, respectively. Further, we aimed to determine postoperative nausea and vomiting (PONV) and pain scores following the laparoscopic cholecystectomy. Methods Patients with American Society of Anesthesiologists (ASA) score of I–III, aged 18 to 75 years and who were scheduled for surgery under general anaesthesia were included in the study. Patients were randomised and a high-dose of 1.2 mg kg−1 rocuronium was given to Group A and 0.6 mg kg−1 rocuronium to Group B. The intraoperative train of four (TOF) ratio and post-tetanic count (PTC) were measured. Surgery was initiated with a low IAP of 7 mmHg. The surgeon evaluated surgical conditions with a 4-step surgical field scale and increased the IAP when necessary. PONV at 4, 12 and 24 hours and postoperative pain at 2 and 24 hours and 3 days were evaluated. Results There were no significant differences in the demographic and haemodynamic parameters between the groups. In high-dose rocuronium Group A, IAP values were significantly lower in the first 20 minutes compared to Group B. The duration of operations was significantly shorter in Group A (29.00±7.39 minute vs. 34.63±12.00 minute, p=0.044). PONV in the first 12 hours was significantly lower in Group A (p<0.05). Conclusion High-dose rocuronium-induced deep neuromuscular block helped perform laparoscopic cholecystectomy operations with lower values of IAP compared to a normal dose rocuronium. It also shortened duration of operation and reduced PONV and pain.

Abstract
BACKGROUND There is increasing evidence for the use of lower insufflation pressures during laparoscopic surgery. Deep neuromuscular blockade allows for a safe reduction in intra-abdominal pressure without compromising the quality of the surgical field. While there is considerable evidence to support superior surgical conditions during deep neuromuscular blockade, there is only a limited amount of studies investigating patient outcomes. Moreover, results are not always consistent between studies and vary between different types of laparoscopic surgery. This study will investigate the effect of low-pressure pneumoperitoneum facilitated by deep NMB on quality of recovery after laparoscopic colorectal surgery. METHODS The RECOVER study is a multicenter double-blinded randomized controlled trial consisting of 204 patients who will be randomized in a 1:1 fashion to group A, low-pressure pneumoperitoneum (8 mmHg) facilitated by deep neuromuscular blockade (post tetanic count of 1-2), or group B, normal-pressure pneumoperitoneum (12 mmHg) with moderate neuromuscular blockade (train-of-four response of 1-2). The primary outcome is quality of recovery on postoperative day 1, quantified by the Quality of Recovery-40 questionnaire. DISCUSSION Few studies have investigated the effect of lower insufflation pressures facilitated by deep neuromuscular blockade on patient outcomes after laparoscopic colorectal procedures. This study will identify whether low pressure pneumoperitoneum and deep neuromuscular blockade will enhance recovery after colorectal laparoscopic surgery and, moreover, if this could be a valuable addition to the Enhanced Recovery After Surgery guidelines.

Abstract
Abstract
Background
It remains uncertain whether individualization of pneumoperitoneum pressures during laparoscopic surgery improves postoperative recovery. This study compared an individualized pneumoperitoneum pressure (IPP) strategy with a standard pneumoperitoneum pressure (SPP) strategy with respect to postoperative recovery after laparoscopic colorectal surgery.
Methods
This was a multicentre RCT. The IPP strategy comprised modified patient positioning, deep neuromuscular blockade, and abdominal wall prestretching targeting the lowest intra-abdominal pressure (IAP) that maintained acceptable workspace. The SPP strategy comprised patient positioning according to the surgeon's preference, moderate neuromuscular blockade and a fixed IAP of 12 mmHg. The primary endpoint was physiological postoperative recovery, assessed by means of the Postoperative Quality of Recovery Scale. Secondary endpoints included recovery in other domains and overall recovery, the occurrence of intraoperative and postoperative complications, duration of hospital stay, and plasma markers of inflammation up to postoperative day 3.
Results
Of 166 patients, 85 received an IPP strategy and 81 an SPP strategy. The IPP strategy was associated with a higher probability of physiological recovery (odds ratio (OR) 2·77, 95 per cent c.i. 1·19 to 6·40, P = 0·017; risk ratio (RR) 1·82, 1·79 to 1·87, P = 0·049). The IPP strategy was also associated with a higher probability of emotional (P = 0·013) and overall (P = 0·011) recovery. Intraoperative adverse events were less frequent with the IPP strategy (P < 0·001) and the plasma neutrophil–lymphocyte ratio was lower (P = 0·029). Other endpoints were not affected.
Conclusion
In this cohort of patients undergoing laparoscopic colorectal surgery, an IPP strategy was associated with faster recovery, fewer intraoperative complications and less inflammation than an SPP strategy. Registration number: NCT02773173 (http://www.clinicaltrials.gov).

Abstract
The influence of the degree of a neuromuscular block (NMB) on surgical operating conditions during laparoscopic surgery is debated controversially. The extent of abdominal distension during the time course of the NMB was assessed as a new measurement tool. In 60 patients scheduled for gynecologic laparoscopic surgery, the increase of the abdominal wall length induced by the capnoperitoneum was measured at 5 degrees of the NMB: intense NMB—post-tetanic count (PTC) = 0; deep NMB—train-of-four count (TOF) = 0 and PTC = 1–5; medium NMB—PTC > 5 and TOF = 0–1; shallow NMB—TOF > 1; full recovery—train-of-four ratio TOFR > 90%. Simultaneously, the quality of operating conditions was assessed with a standardized rating scale (SRS) reaching from 1 (extremely poor conditions) to 5 (excellent conditions). Fifty patients could be included in the analysis. The abdominal wall length increased by 10–13 mm induced by the capnoperitoneum. SRS was higher during intense NMB (4.7 ± 0.5) vs. full recovery (4.5 ± 0.5) (mean ± SD; p = 0.025). Generally, an intense NMB did not increase abdominal wall length induced by capnoperitoneum. Additionally, its influence on the quality of surgical operating conditions seems to be of minor clinical relevance.

Wei Y, Li J, Sun F, Zhang D, Li M, Zuo Y. Low intra-abdominal pressure and deep neuromuscular blockade laparoscopic surgery and surgical space conditions: A meta-analysis. Medicine (Baltimore) 2020; 99:e19323. [PMID: 32118762 PMCID: PMC7478474 DOI: 10.1097/md.0000000000019323] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2019] [Revised: 01/13/2020] [Accepted: 01/25/2020] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Low intra-abdominal pressure (IAP) and deep neuromuscular blockade (NMB) are frequently used in laparoscopic abdominal surgery to improve surgical space conditions and decrease postoperative pain. The evidence supporting operations using low IAP and deep NMB is open to debate. METHODS The feasibility of the routine use of low IAP +deep NMB during laparoscopic surgery was examined. A meta-analysis is conducted with randomized controlled trials (RCTs) to compare the influence of low IAP + deep NMB vs. low IAP + moderate NMB, standard IAP +deep NMB, and standard IAP + moderate NMB during laparoscopic procedures on surgical space conditions, the duration of surgery and postoperative pain. RCTs were identified using the Cochrane, Embase, PubMed, and Web of Science databases from initiation to June 2019. Our search identified 9 eligible studies on the use of low IAP + deep NMB and surgical space conditions. RESULTS Low IAP + deep NMB during laparoscopic surgery did not improve the surgical space conditions when compared with the use of moderate NMB, with a mean difference (MD) of -0.09 (95% confidence interval (CI): -0.55-0.37). Subgroup analyses showed improved surgical space conditions with the use of low IAP + deep NMB compared with low IAP + moderate NMB, (MD = 0.63 [95% CI:0.06-1.19]), and slightly worse conditions compared with the use of standard IAP + deep NMB and standard IAP + moderate NMB, with MDs of -1.13(95% CI:-1.47 to 0.79) and -0.87(95% CI:-1.30 to 0.43), respectively. The duration of surgery did not improve with low IAP + deep NMB, (MD = 1.72 [95% CI: -1.69 to 5.14]), and no significant reduction in early postoperative pain was found in the deep-NMB group (MD = -0.14 [95% CI: -0.51 to 0.23]). CONCLUSION Low IAP +deep NMB is not significantly more effective than other IAP +NMB combinations for optimizing surgical space conditions, duration of surgery, or postoperative pain in this meta-analysis. Whether the use of low IAP + deep NMB results in fewer intraoperative complications, enhanced quality of recovery or both after laparoscopic surgery should be studied in the future.

Abstract
Neuromuscular blockade (TOF count = 0) can improve tracheal intubation and microlaryngeal surgery. It is also frequently used in many surgical fields including both nonlaparoscopic and laparoscopic surgery to improve surgical conditions and to prevent sudden muscle contractions. Currently there is a controversy regarding the need and the clinical benefits of deep neuromuscular blockade for different surgical procedures. Deep neuromuscular relaxation improves laparoscopic surgical space conditions only marginally when using low intra-abdominal pressure. There is no outcome-relevant advantage of low compared to higher intra-abdominal pressures, but worsen the surgical conditions. Postoperative, residual curarisation can be avoided by algorithm-based pharmacological reversing and quantitative neuromuscular monitoring.

Comparison of Operating Conditions, Postoperative Pain and Recovery, and Overall Satisfaction of Surgeons with Deep vs. No Neuromuscular Blockade for Spinal Surgery under General Anesthesia: A Prospective Randomized Controlled Trial. J Clin Med 2019; 8:jcm8040498. [PMID: 31013693 PMCID: PMC6518127 DOI: 10.3390/jcm8040498] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 04/02/2019] [Accepted: 04/09/2019] [Indexed: 02/07/2023] Open
Abstract
We aimed to investigate operating conditions, postoperative pain, and overall satisfaction of surgeons using deep neuromuscular blockade (NMB) vs. no NMB in patients undergoing lumbar spinal surgery under general anesthesia. Eighty-three patients undergoing lumbar fusion were randomly assigned to receive deep NMB (n = 43) or no NMB (n = 40). In the deep-NMB group, rocuronium was administered to maintain deep NMB (train-of-four count 0, post-tetanic count 1–2) until the end of surgery. In the no-NMB group, sugammadex 4 mg/kg at train-of-four (TOF) count 0–1 or sugammadex 2 mg/kg at TOF count ≥2 was administered to reverse the NMB 10 min after placing the patient prone. Peak inspiratory airway pressure, plateau airway pressure, lumbar retractor pressure significantly were lower in the deep-NMB group. Degree of surgical field bleeding (0–5), muscle tone (1–3), and satisfaction (1–10) rated by the surgeon were all superior in the deep-NMB group. Pain scores, rescue fentanyl consumption in post-anesthesia care unit (PACU), and postoperative patient-controlled analgesia consumption were significantly lower in the deep-NMB group, and this group had a shorter length of stay in PACU. Compared to no NMB, deep NMB provides better operating conditions, reduced postoperative pain and higher overall satisfaction in lumbar spinal surgery.

Abstract
Background A recent study shows that a multifaceted strategy using an individualised intra-abdominal pressure titration strategy during colorectal laparoscopic surgery results in an acceptable workspace at low intra-abdominal pressure in most patients. The multifaceted strategy, focused on lower to individualised intra-abdominal pressures, includes prestretching the abdominal wall during initial insufflation, deep neuromuscular blockade, low tidal volume ventilation settings and a modified lithotomy position. The study presented here tests the hypothesis that this strategy improves outcomes of patients scheduled for colorectal laparoscopic surgery. Methods The Individualized Pneumoperitoneum Pressure in Colorectal Laparoscopic Surgery versus Standard Therapy (IPPCollapse-II) study is a multicentre, two-arm, parallel-group, single-blinded randomised 1:1 clinical study that runs in four academic hospitals in Spain. Patients scheduled for colorectal laparoscopic surgery with American Society of Anesthesiologists classification I to III who are aged > 18 years and are without cognitive deficits are randomised to an individualised pneumoperitoneum pressure strategy (the intervention group) or to a conventional pneumoperitoneum pressure strategy (the control group). The primary outcome is recovery assessed with the Post-operative Quality of Recovery Scale (PQRS) at postoperative day 1. Secondary outcomes include PQRS score in the post anaesthesia care unit and at postoperative day 3, postoperative complications until postoperative day 28, hospital length of stay and process-related outcomes. Discussion The IPPCollapse-II study will be the first randomised clinical study that assesses the impact of an individualised pneumoperitoneum pressure strategy focused on working with the lowest intra-abdominal pressure during colorectal laparoscopic surgery on relevant patient-centred outcomes. The results of this large study, to be disseminated through conference presentations and publications in international peer-reviewed journals, are of ultimate importance for optimising the care and safety of laparoscopic abdominal surgery. Selection of patient-reported outcomes as the primary outcome of this study facilitates the translation into clinical practice. Access to source data will be made available through anonymised datasets upon request and after agreement of the Steering Committee of the IPPCollapse-II study.

Abstract
INTRODUCTION Proper management of patients undergoing robotic-assisted urologic and gynecologic surgery must consider a series of peculiarities in the procedures for anesthesiology, critical care medicine, respiratory care, and pain management. Although the indications for robotic-assisted urogynecologic surgeries have increased in recent years, specific guidance documents are still lacking. EVIDENCE ACQUISITION A multidisciplinary group including anesthesiologists, gynecologists, urologists, and a clinical epidemiologist systematically reviewed the relevant literature and provided a set of recommendations and unmet needs on peculiar aspects of anesthesia in this field. EVIDENCE SYNTHESIS Nine core contents were identified, according to their requirements in urogynecologic robotic-assisted surgery: patient position, pneumoperitoneum and ventilation strategies, hemodynamic variations and fluid therapy, neuromuscular block, renal surgery and prevention of acute kidney injury, monitoring the Department of anesthesia, postoperative delirium and cognitive dysfunction, prevention of postoperative nausea and vomiting, and pain management in endometriosis. CONCLUSIONS This consensus document provides guidance for the management of urologic and gynecologic patients scheduled for robotic-assisted surgery. Moreover, the identified unmet needs highlight the requirement for further prospective randomized studies.

Abstract
INTRODUCTION Surgical rating scales (SRSs) enable the surgeon to uniformly quantify surgical working conditions. They are increasingly used as a primary outcome in studies evaluating the effect of anaesthesia or surgery-related interventions on the quality of the surgical work field. SRSs are especially used in laparoscopic surgery due to a renewed interest in deep neuromuscular block. There are however no guidelines regarding the uniform use of SRS and the uniform reporting of results. METHODS A systematic search was conducted in the databases of PubMed, Web of Science and Embase for studies that reported the use of an SRS to evaluate surgical conditions in laparoscopic surgery. Only original human research in English language with full text availability through the Leiden university library was considered for this review. The full texts of eligible abstracts were independently reviewed by the first and second author. The quality of SRSs and methodology of rating were systematically reviewed. RESULTS The search yielded 2830 reports, of which 17 were identified using a surgical rating scale (SRS) in laparoscopic surgery. Ten of these reports used a unique SRS, these were systematically appraised for their quality. The overall quality of the SRSs was low: the majority of the scales were poorly described and lacked assessment of inter- and intra-rater reliability. In addition, considerable differences exist in the methodology of rating and the reporting of results. CONCLUSION There is substantial inconsistency in SRS quality, methodology, and results reporting. The uniform use of high-quality surgical rating scales is needed to improve the quality and reproducibility of future research.

Abstract
BACKGROUND While guidelines for laparoscopic abdominal surgery advise using the lowest possible intra-abdominal pressure, commonly a standard pressure is used. We evaluated the feasibility of a predefined multifaceted individualized pneumoperitoneum strategy aiming at the lowest possible intra-abdominal pressure during laparoscopic colorectal surgery. METHODS Multicenter prospective study in patients scheduled for laparoscopic colorectal surgery. The strategy consisted of ventilation with low tidal volume, a modified lithotomy position, deep neuromuscular blockade, pre-stretching of the abdominal wall, and individualized intra-abdominal pressure titration; the effect was blindly evaluated by the surgeon. The primary endpoint was the proportion of surgical procedures completed at each individualized intra-abdominal pressure level. Secondary endpoints were the respiratory system driving pressure, and the estimated volume of insufflated CO2 gas needed to perform the surgical procedure. RESULTS Ninety-two patients were enrolled in the study. Fourteen cases were converted to open surgery for reasons not related to the strategy. The intervention was feasible in all patients and well-accepted by all surgeons. In 61 out of 78 patients (78%), surgery was performed and completed at the lowest possible IAP, 8 mmHg. In 17 patients, IAP was raised up to 12 mmHg. The relationship between IAP and driving pressure was almost linear. The mean estimated intra-abdominal CO2 volume at which surgery was performed was 3.2 L. CONCLUSION A multifaceted individualized pneumoperitoneum strategy during laparoscopic colorectal surgery was feasible and resulted in an adequate working space in most patients at lower intra-abdominal pressure and lower respiratory driving pressure.

Abstract
Background Laparoscopic surgery typically requires deep neuromuscular blockade (NMB), but whether deep or moderate NMB is superior for thoracoscopic surgery remains controversial. Methods Patients scheduled for thoracoscopic lobectomy under intravenous anesthesia were randomly assigned to receive moderate [train of four (TOF) 1–2] or deep NMB [TOF 0, post-tetanic count (PTC) 1–5]. Depth of anesthesia was controlled at a Narcotrend rating of 30 ± 5 in both groups. The primary outcome was the need to use an additional muscle relaxant (cisatracurium) during surgery. Secondary outcomes included surgeon satisfaction, recovery time of each stage after drug withdrawal [time from withdrawal until TOF recovery to 20% (antagonists administration), 25, 75, 90, 100%], blood gas data, VAS pain grade after extubation, the time it takes for patients to begin walking after surgery, postoperative complications and hospitalization time. Results were analyzed on an intention-to-treat basis. Results Thirty patients were enrolled per arm, and all but one patient in each arm was included in the final analysis. Among patients undergoing moderate NMB, surgeons applied additional cisatracurium in 8 patients because of body movement and 5 because of coughing (13/29, 44.8%). Additional cisatracurium was not applied to any of the patients undergoing deep NMB (p < 0.001). Surgeons reported significantly higher satisfaction for patients undergoing deep NMB (p < 0.001, Wilcoxon rank sum test). The mean difference between the two groups in the time from withdrawal until TOF recovery of 25% or 90% was 10 min (p < 0.001). The two groups were similar in other recovery data, blood gas analysis, VAS pain grade, days for beginning to walk and mean hospitalization time. Conclusions Deep NMB can reduce the use of additional muscle relaxant and increase surgeon satisfaction during thoracoscopic lobectomy.

Abstract
Fifty-four pigs ( Sus scrofa, Large White cross) from a commercial pig farm were anaesthetised over a six-year period from October 2011. The procedural stages included initial instrumentation for intra-operative monitoring, laparoscopic nephrectomy, preparation of the kidney graft, orthotopic auto-transplantation by either a laparoscopic approach or an open surgical approach, and ligation of the contralateral ureter. During the evolution and establishment of this pig model multiple refinements were introduced: (1) a heat pad was changed to a circulating warm air blanket; (2) routine administration of anticholinesterase and antimuscarinic drugs for reversal of neuromuscular blockade; (3) a technique for urethral catheterisation was developed; (4) ultrasound guidance for placement of a central venous line was learned; (5) intravenous infusions of morphine and ketamine were instituted for a more stable and balanced anaesthetic protocol; and (6) post-operative monitoring was performed by two technical staff for at least the first six hours after extubation of the trachea. The combination of refinements to the anaesthesia protocol for laparoscopic orthotopic kidney auto-transplantation over the first 54 pigs has translated to improved outcomes. This conclusion is entirely subjective as accurate measurement of the impact of each refinement is impossible. Nevertheless, refinement is a continuous process and should be applied to the entire range of procedures involved in animal use for scientific purposes.
