C.- Use of Sugammadex after Neostigmine Incomplete Reversal of Rocuronium-Induced Neuromuscular Blockade(2012) MENEZES, Cassio Campelo de; PECEGUINI, Lilian Akemi Moore; SILVA, Enis Donizetti; SIMOES, Claudia MarquezMenezes CC, Peceguini LAM, Silva ED, Simoes CM Use of Sugammadex after Neostigmine Incomplete Reversal of Rocuronium-Induced Neuromuscular Blockade. Background and objectives: Neuromuscular blockers (NMB) have been used for more than half of a century in anesthesia and have always been a challenge for anesthesiologists. Until recently, the reversal of nondepolarizing neuromuscular blockers had only one option: the use of anticholinesterase agents. However, in some situations, such as deep neuromuscular blockade after high doses of relaxant, the use of anticholinesterase agents does not allow adequate reversal of neuromuscular blockade: Recently, sugammadex, a gamma-cyclodextrin, proved to be highly effective for reversal of NMB induced by steroidal agents. Case report: A female patient who underwent an emergency exploratory laparotomy after rapid sequence intubation with rocuronium 1.2 mg.kg(-1). At the end of surgery, the pat ent received neostigmine reversal of NMB. However, neuromuscular junction monitoring did not show the expected recovery, presenting residual paralysis. Sugammadex 2 mg.kg(-1) was used and the patient had complete reversal of NMB in just 2 minutes time. Conclusion: Adequate recovery of residual neuromuscular blockade is required for full control of the pharynx and respiratory functions in order to prevent complications. Adequate recovery can only be obtained by neuromuscular junction monitoring with TOF ratio greater than 0.9. Often, the reversal of NMB with anticholinesterase drugs may not be completely reversed. However, in the absence of objective monitoring this diagnosis is not possible. The case illustrates the diagnosis of residual NMB even after reversal with anticholinesterase agents, resolved with the administration of sugammadex, a safe alternative to reverse the NMB induced by steroidal non-depolarizing agents.
- Effect of postoperative goal-directed therapy in cancer patients undergoing high-risk surgery: a randomized clinical trial and meta-analysis(2018) GERENT, Aline Rejane Muller; ALMEIDA, Juliano Pinheiro; FOMINSKIY, Evgeny; LANDONI, Giovanni; OLIVEIRA, Gisele Queiroz de; RIZK, Stephanie Itala; FUKUSHIMA, Julia Tizue; SIMOES, Claudia Marques; RIBEIRO JR., Ulysses; PARK, Clarice Lee; NAKAMURA, Rosana Ely; FRANCO, Rafael Alves; CANDIDO, Patricia Ines; TAVARES, Cintia Rosa; CAMARA, Ligia; FERREIRA, Graziela dos Santos Rocha; ALMEIDA, Elisangela Pinto Marinho de; KALIL FILHO, Roberto; GALAS, Filomena Regina Barbosa Gomes; HAJJAR, Ludhmila AbrahaoBackground: Perioperative goal-directed hemodynamic therapy (GDHT) has been advocated in high-risk patients undergoing noncardiac surgery to reduce postoperative morbidity and mortality. We hypothesized that using cardiac index (CI)-guided GDHT in the postoperative period for patients undergoing high-risk surgery for cancer treatment would reduce 30-day mortality and postoperative complications. Methods: A randomized, parallel-group, superiority trial was performed in a tertiary oncology hospital. All adult patients undergoing high-risk cancer surgery who required intensive care unit admission were randomly allocated to a CI-guided GDHT group or to a usual care group. In the GDHT group, postoperative therapy aimed at CI >= 2.5 L/min/m(2) using fluids, inotropes and red blood cells during the first 8 postoperative hours. The primary outcome was a composite endpoint of 30-day all-cause mortality and severe postoperative complications during the hospital stay. A meta-analysis was also conducted including all randomized trials of postoperative GDHT published from 1966 to May 2017. Results: A total of 128 patients (64 in each group) were randomized. The primary outcome occurred in 34 patients of the GDHT group and in 28 patients of the usual care group (53.1% vs 43.8%, absolute difference 9.4 (95% CI, -7.8 to 25.8); p = 0.3). During the 8-h intervention period more patients in the GDHT group received dobutamine when compared to the usual care group (55% vs 16%, p < 0.001). A meta-analysis of nine randomized trials showed no differences in postoperative mortality (risk ratio 0.85, 95% CI 0.59-1.23; p = 0.4; p for heterogeneity = 0.7; I-2 = 0%) and in the overall complications rate (risk ratio 0.88, 95% CI 0.71-1.08; p = 0.2; p for heterogeneity = 0.07; I-2 = 48%), but a reduced hospital length of stay in the GDHT group (mean difference (MD) - 1.6; 95% CI - 2.75 to -0.46; p = 0.006; p for heterogeneity = 0.002; I-2 = 74%). Conclusions: CI-guided hemodynamic therapy in the first 8 postoperative hours does not reduce 30-day mortality and severe complications during hospital stay when compared to usual care in cancer patients undergoing high-risk surgery.
- A pragmatic multi-center trial of goal-directed fluid management based on pulse pressure variation monitoring during high-risk surgery(2017) MALBOUISSON, Luiz Marcelo Sa; SILVA JR., Joao Manoel; CARMONA, Maria Jose Carvalho; LOPES, Marcel Rezende; ASSUNCAO, Murilo Santucci; VALIATTI, Jorge Luis dos Santos; SIMOES, Claudia Marques; AULER JR., Jose Otavio CostaBackground: Intraoperative fluid therapy guided by mechanical ventilation-induced pulse-pressure variation (PPV) may improve outcomes after major surgery. We tested this hypothesis in a multi-center study. Methods: The patients were included in two periods: a first control period (control group; n = 147) in which intraoperative fluids were given according to clinical judgment. After a training period, intraoperative fluid management was titrated to maintain PPV < 10% in 109 surgical patients (PPV group). We performed 1:1 propensity score matching to ensure the groups were comparable with regard to age, weight, duration of surgery, and type of operation. The primary endpoint was postoperative hospital length of stay. Results: After matching, 84 patients remained in each group. Baseline characteristics, surgical procedure duration and physiological parameters evaluated at the start of surgery were similar between the groups. The volume of crystalloids (4500 mL [3200-6500 mL] versus 5000 mL [3750-8862 mL]; P = 0.01), the number of blood units infused during the surgery (1.7 U [0.9-2.0 U] versus 2.0 U [1.7-2.6 U]; P = 0.01), the fraction of patients transfused (13.1% versus 32.1%; P = 0.003) and the number of patients receiving mechanical ventilation at 24 h (3.2% versus 9.7%; P = 0.027) were smaller postoperatively in PPV group. Intraoperative PPV-based improved the composite outcome of postoperative complications OR 0.59 [95% CI 0.35-0.99] and reduced the postoperative hospital length of stay (8 days [6-14 days] versus 11 days [7-18 days]; P = 0.01). Conclusions: In high-risk surgeries, PPV-directed volume loading improved postoperative outcomes and decreased the postoperative hospital length of stay.
- Prevention of drug diversion and substance use disorders among anesthesiologists: a narrative review(2023) FITZSIMONS, Michael G.; SOUSA, Gabriel Soares de; GALSTYAN, Arpine; QUINTAO, Vinicius Caldeira; SIMOES, Claudia MarquezDiversion of substances from the care of the intended patient is a significant problem in healthcare. Patients are harmed by the undertreatment of pain and suffering, transmission of disease, as well as the risk associated with impaired vigilance. Healthcare providers may be harmed by the physical and mental impact of their addictions. Healthcare systems are placed in jeopardy by the legal impact associated with illegal routes of drug release including sanction and financial liability and loss of public trust. Healthcare institutions have implemented many measures to reduce diversion from the perioperative area. These efforts include education, medical record surveillance, automated medication dispensing systems, urine drug testing, substance waste management systems, and drug diversion prevention teams. This narrative review evaluates strengths, weaknesses, and effectiveness of these systems and provides recommendations for leaders and care providers. (c) 2023 Sociedade Brasileira de Anestesiologia.
- Drug abuse amongst anesthetists in Brazil: a national survey(2021) SOUSA, Gabriel Soares de; FITZSIMONS, Michael Gerald; MUELLER, Ariel; QUINTAO, Vinicius Caldeira; SIMOES, Claudia MarquezBackground: The prevalence of Substance Use Disorders (SUD) and acceptance of drug testing among anesthetists in Brazil has not been determined. Methods: An intemet-based survey was performed to investigate the prevalence of SUD among anesthetists in Brazil, to explore the attitudes of anesthetists regarding whether SUD jeopardizes the health of an impaired provider or their patient, and to determine the provider's perspective regarding acceptance and effectiveness of drug testing to reduce SUD. The questionnaire was distributed via social media. REDCap was utilized to capture data. A sample size of 350 to achieve a confidence level of 95% and confidence interval of 5 was estimated. Study report was based on STROBE and CHERRIES statements. Results: The survey was returned from 1,295 individuals. Most individuals knew an anesthesia provider with a SUD (82.07%), while 23% admitted personal use. The most common identified substances of abuse were opioids (67.05%). Very few respondents worked in a setting that performs drug testing (n = 17, 1.33%). Most individuals believed that drug testing could improve personal safety (82.83%) or the safety of patients (85.41%). Individuals with a personal history of SUD were less likely to believe in the effectiveness of drug testing to reduce one's own risk (74.92% vs. 85.18%, p < 0.0001) or improve the safety of patients (76.27% vs. 88.13%, p < 0.001). Conclusions: SUDs are common among anesthetists in Brazil. Drug testing would be accepted as a viable means to reduce the incidence although a larger study should be performed to investigate the logistical feasibility.

There are multiple risk scores applied to predict different outcomes. However, specific populations as patients with cancer may have specific risk factors, so it is needed to evaluate if global risk scoresas ASA and POSSUM or P POSSUM are able to assist the surgical team. Objective: To retrospectively assess the value of the ASA classification (American Society of Anesthesiology), POSSUM (Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity), and Porthsmouth POSSUM in prediction of hospital mortality in patients with cancer undergoing abdominal surgery. Methods: Three hundred and thirteen patients who under-went three hundred and nineteen oncologic abdominal surgeries were evaluated using ASA, POSSUM and Porthsmouth-POSSUM in relation to hospital mortality. The variables observed were: age, gender, ASA classification, pul- monary diseases, cardiovascular diseases, preoperative sys-tolic arterial pressure and cardiac rate, Glasgow scale, urea, potassium, sodium, hemoglobin, white cell count, number of simultaneous surgical procedures, observed blood losses, peritoneal contamination, oncological disease and dissemination, elective, emergent or urgent surgery, intensive care support and hospital mortality. Results: The overall hospital mortality rate was 5.59%. These results showed that POSSUM over predicted in-hospital deaths when compared to American Society of Anesthesiologists classification (relative risk, 0.55; P=.07) and Porths- mouth POSSUM (relative risk, 0,43; P=.0007) didn’t equally correspond to ASA predicted perioperative mortality. All evaluated scores didn’t equally predict observed mortality as the standardized mortality rate was 2.25 for ASA classification, 0.4 for POSSUM and 0.8 for P-POSSUM. Conclusion: The ASA classification, POSSUM and P POSSUM scores were not useful in predicting perioperative mortality for patients with cancer submitted to abdominal surgeries. It is needed to evaluate specific populations to adjust the existing perioperative prediction scores to serve as objective methods to assist the surgical team in classifying patients into risk groups with different probabilities of perioperative complications. ASA classification is based mainly on subjective clinical judgments and probably POSUUM and P-POSSUM need to have the equations balanced to specific populations.
