- Predictors and their prognostic value for no ROSC and mortality after a non-cardiac surgery intraoperative cardiac arrest: a retrospective cohort study(2019) VANE, Matheus F.; CARMONA, Maria J. C.; PEREIRA, Sergio M.; KERN, Karl B.; TIMERMAN, Sergio; PEREZ, Guilherme; VANE, Luiz Antonio; OTSUKI, Denise Aya; JR, Jose O. C. AulerData on predictors of intraoperative cardiac arrest (ICA) outcomes are scarce in the literature. This study analysed predictors of poor outcome and their prognostic value after an ICA. Clinical and laboratory data before and 24 hours (h) after ICA were analysed as predictors for no return of spontaneous circulation (ROSC) and 24 h and 1-year mortality. Receiver operating characteristic curves for each predictor and sensitivity, specificity, positive and negative likelihood ratios, and post-test probability were calculated. A total of 167,574 anaesthetic procedures were performed, including 158 cases of ICAs. Based on the predictors for no ROSC, a threshold of 13 minutes of ICA yielded the highest area under curve (AUC) (0.867[0.80-0.93]), with a sensitivity and specificity of 78.4% [69.6-86.3%] and 89.3% [80.4-96.4%], respectively. For the 1-year mortality, the GCS without the verbal component 24 h after an ICA had the highest AUC (0.616 [0.792-0.956]), with a sensitivity of 79.3% [65.5-93.1%] and specificity of 86.1 [74.4-95.4]. ICA duration and GCS 24 h after the event had the best prognostic value for no ROSC and 1-year mortality. For 24 h mortality, no predictors had prognostic value.
conferenceObject Investigation of the DNA methylation profile in children presenting emergence delirium(2021) QUINTAO, Vinicius; KULIKOWSKI, Leslie; CARMONA, Maria- Specific questionnaire detects a high incidence of intra-operative hypersensitivity reactions(2018) GARRO, Laila S.; V, Marcelo Aun; SOARES, Iracy Silvia C.; RIBEIRO, Marisa R.; MOTTA, Antonio A.; KALIL, Jorge; CASTELLS, Mariana C.; CARMONA, Maria Jose C.; GIAVINA-BIANCHI, PedroOBJECTIVE: To assess the incidence of intra-operative immediate hypersensitivity reactions and anaphylaxis. METHODS: A cross-sectional observational study was conducted at the Department of Anesthesiology, University of Sao Paulo School of Medicine, Hospital das Clinicas, Sao Paulo, Brazil, from January to December 2010. We developed a specific questionnaire to be completed by anesthesiologists. This tool included questions about hypersensitivity reactions during anesthesia and provided treatments. We included patients with clinical signs compatible with immediate hypersensitivity reactions. Hhypersensitivity reactions were categorized according to severity (grades I-V). American Society of Anesthesiologists physical status classification (ASA 1-6) was analyzed and associated with the severity of hypersensitivity reactions. RESULTS: In 2010, 21,464 surgeries were performed under general anesthesia. Anesthesiologists answered questionnaires on 5,414 procedures (25.2%). Sixty cases of intra-operative hypersensitivity reactions were reported. The majority patients (45, 75%) had hypersensitivity reactions grade I reactions (incidence of 27.9:10,000). Fifteen patients (25%) had grade II, III or IV reactions (intra-operative anaphylaxis) (incidence of 7:10,000). No patients had grade V reactions. Thirty patients (50%) were classified as ASA 1. The frequency of cardiovascular shock was higher in patients classified as ASA 3 than in patients classified as ASA 1 or ASA 2. Epinephrine was administered in 20% of patients with grade III hypersensitivity reactions and in 50% of patients with grade II hypersensitivity reactions. CONCLUSIONS: The majority of patients had hypersensitivity reactions grade I reactions; however, the incidence of intra-operative anaphylaxis was higher than that previously reported in the literature. Patients with ASA 3 had more severe anaphylaxis; however, the use of epinephrine was not prescribed in all of these cases. Allergists and anesthesiologists should implement preventive measures to reduce the occurrence of anaphylaxis.
- Comparison of intravenous and inhalation anesthesia on postoperative behavior changes in children undergoing ambulatory endoscopic procedures: A randomized clinical trial(2023) QUINTAO, Vinicius Caldeira; CARLOS, Ricardo Vieira; CARDOSO, Priscilla Ferreira Neto; ZEFERINO, Suely Pereira; KULIKOWSKI, Leslie Domenici; LEE-ARCHER, Paul; CARMONA, Maria Jose CarvalhoBackgroundEarly and delayed behavioral changes are well recognized after anesthesia. Intravenous anesthesia may prevent emergence delirium. However, it has not been evaluated as a preventive strategy for delayed postoperative behavior changes. AimsWe aimed to determine whether intravenous anesthesia is effective at reducing postoperative behavior changes in children undergoing ambulatory endoscopic procedures when compared to inhalation anesthesia. MethodsThis randomized, double-blinded controlled trial was approved by the local IRB. Children aged 1-12 years who underwent ambulatory endoscopic procedures were recruited. Preoperative anxiety was evaluated through the modified Yale Preoperative Anxiety Scale. All children underwent face mask inhalation induction with sevoflurane. After a peripheral line was placed, each child was allocated to sevoflurane or propofol maintenance. Emergence delirium was evaluated through the Pediatric Anesthesia Emergence Delirium scale. The child was discharged home, and behavioral changes were assessed through the Posthospitalization Behavior Questionnaire for Ambulatory Surgery on Days 1, 7, and 14. ResultsOverall, 175 children were enrolled. On Day 1 after the procedure, 57 children presented at least one negative behavior. On Days 7 and 14, 49 and 44 children presented at least one negative behavior, respectively. The median number of negative behaviors was similar between the groups. Post hoc analyses showed a moderate correlation between emergence delirium and negative postoperative behavior on Day 7 (r = .34; p = <.001) and an increase of 3.31 (95% CI 1.90; 4.36 p < .001) points in the mean summed score of new negative behaviors for individuals with emergence delirium. ConclusionThe incidence of postoperative behavior changes in children undergoing ambulatory endoscopic procedures was similar when comparing intravenous with inhalation anesthesia. Children who experience emergence delirium might show a greater incidence of negative postoperative behavior changes.
- Intraoperative pulmonary hyperdistention estimated by transthoracic lung ultrasound: A pilot study(2020) TONELOTTO, Bruno; PEREIRA, Sergio Martins; TUCCI, Mauro Roberto; VAZ, Diogo Florenzano; VIEIRA, Joaquim Edson; MALBOUISSON, Luiz Marcelo; GAY, Frederick; SIMOES, Claudia Marquez; CARMONA, Maria Jose Carvalho; MONSEL, Antoine; AMATO, Marcelo Brito; ROUBY, Jean-Jacques; JR, Jose Otavio Costa AulerIntroduction: Transthoracic lung ultrasound can assess atelectasis reversal and is considered as unable to detect associated hyperdistention. In this study, we describe an ultrasound pattern highly suggestive of pulmonary hyperdistention. Methods: Eighteen patients with normal lungs undergoing lower abdominal surgery were studied. Electrical impedance tomography was calibrated, followed by anaesthetic induction, intubation and mechanical ventilation. To reverse posterior atelectasis, a recruitment manoeuvre was performed. Positive-end expiratory pressure (PEEP) titration was then obtained during a descending trial - 20, 18, 16, 14, 12, 10, 8, 6 and 4 cmH(2)O. Ultrasound and electrical impedance tomography data were collected at each PEEP level and interpreted by two independent observers. Spearman correlation test and receiving operating characteristic curve were used to compare lung ultrasound and electrical impedance tomography data. Results: The number of horizontal A lines increased linearly with PEEP: from 3 (0, 5) at PEEP 4 cmH(2)O to 10 (8, 13) at PEEP 20 cmH(2)O. The increase number of A lines was associated with a parallel and significant decrease in intercostal space thickness (p = 0.001). The lung ultrasound threshold for detecting pulmonary hyperdistention was defined as the number of A lines counted at the PEEP preceding the PEEP providing the best respiratory compliance. Six A lines was the median threshold for detecting pulmonary hyperdistention. The area under the receiving operating characteristic curve was 0.947. Conclusions: Intraoperative transthoracic lung ultrasound can detect lung hyperdistention during a PEEP descending trial. Six or more A lines detected in normally aerated regions can be considered as indicating lung hyperdistention.
- Opioids and premature biochemical recurrence of prostate cancer: a randomised prospective clinical trial(2021) RANGEL, Felipe P.; JR, Jose O. C. Auler; CARMONA, Maria J. C.; CORDEIRO, Mauricio D.; NAHAS, William C.; COELHO, Rafael F.; SIMOES, Claudia M.Background: Prostate cancer is one of the most prevalent neoplasms in male patients, and surgery is the main treatment. Opioids can have immune modulating effects, but their relation to cancer recurrence is unclear. We evaluated whether opioids used during prostatectomy can affect biochemical recurrence-free survival. Methods: We randomised 146 patients with prostate cancer scheduled for prostatectomy into opioid-free anaesthesia or opioid-based anaesthesia groups. Baseline characteristics, perioperative data, and level of prostate-specific antigen every 6 months for 2 yr after surgery were recorded. Prostate-specific antigen >0.2 ng ml(-1) was considered biochemical recurrence. A survival analysis compared time with biochemical recurrence between the groups, and a Cox regression was modelled to evaluate which variables affect biochemical recurrence-free survival. Results: We observed 31 biochemical recurrence events: 17 in the opioid-free anaesthesia group and 14 in the opioidbased anaesthesia group. Biochemical recurrence-free survival was not statistically different between groups (P=0.54). Cox regression revealed that biochemical recurrence-free survival was shorter in cases of obesity (hazard ratio [HR] 1.63, confidence interval [CI] 0.16-3.10; p=0.03), high D'Amico risk (HR 1.58, CI 0.35-2.81; P=0.012), laparoscopic surgery (HR 1.6, CI 0.38-2.84; P=0.01), stage 3 tumour pathology (HR 1.60, CI 0.20-299) and N1 status (HR 1.34, CI 0.28-2.41), and positive surgical margins (HR 1.37, CI 0.50-2.24; P=0.002). The anaesthesia technique did not affect time to biochemical recurrence (HR -1.03, CI -2.65-0.49; P=0.18). Conclusions: Intraoperative opioid use did not modify biochemical recurrence rates and biochemical recurrence-free survival in patients with intermediate and high D?Amico risk prostate cancer undergoing radical prostatectomy. Clinical trial registration: NCT03212456.
- Outcomes of patients with trauma and intraoperative cardiac arrest(2013) TOLEDO, Flavia O.; GONZALEZ, Maria M.; SEBBAG, Ilana; LELIS, Rolison G. B.; ARANHA, Gustavo F.; TIMERMAN, Sergio; CARMONA, Maria J. C.Background: Although the occurrence of intraoperative cardiac arrest is rare, it is a severe adverse event with a high mortality rate. Trauma patients have additional causes for intraoperative arrest, and we hypothesised that the survival of trauma patients who experienced intraoperative cardiac arrest would be worse than nontrauma patients who experienced intraoperative cardiac arrest. Objectives: The aim of the present study was to compare the outcomes of trauma and nontrauma patients after intraoperative cardiac arrest. Methods: In a tertiary university hospital and trauma centre, the intraoperative cardiac arrest cases were evaluated from January 2007 to December 2009, excluding patients submitted to cardiac surgery. Data were prospectively collected using the Utstein-style. Outcomes among the patients with trauma were compared to the patients without trauma. Results: We collected data from 81 consecutive intraoperative cardiac arrest cases: 32 with trauma and 49 without trauma. Patients in the trauma group were younger than the patients in the nontrauma group (44 +/- 23 vs. 63 +/- 17, p < 0.001). Hypovolaemia (63% vs. 35%, p = 0.022) and metabolic/hydroelectrolytic disturbances (41% vs. 2%, p < 0.001) were more likely to cause the cardiac arrest in the trauma group. The first documented arrest rhythm did not differ between the groups, and pulseless electrical activity was the most prevalent rhythm (66% vs. 53%, p = 0.698). The return of spontaneous circulation (47% vs. 63%, p = 0.146) and survival to discharge with favourable neurological outcome (16% vs. 14%, p = 0.869) did not differ between the two groups. Conclusions: The outcomes did not differ between patients with trauma and nontrauma intraoperative cardiac arrest.
- Perioperative cardiac arrest: an evolutionary analysis of the intra-operative cardiac arrest incidence in tertiary centers in Brazil(2016) VANE, Matheus Fachini; NUZZI, Rafael Ximenes do Prado; ARANHA, Gustavo Fabio; LUZ, Vinicius Fernando da; MALBOUISSON, Luiz Marcelo Sa; GONZALEZ, Maria Margarita Castro; AULER, Jose Otavio Costa; CARMONA, Maria Jose CarvalhoBackground: Great changes in medicine have taken place over the last 25 years worldwide. These changes in technologies, patient risks, patient profile, and laws regulating the medicine have impacted the incidence of cardiac arrest. It has been postulated that the incidence of intraoperative cardiac arrest has decreased over the years, especially in developed countries. The authors hypothesized that, as in the rest of the world, the incidence of intraoperative cardiac arrest is decreasing in Brazil, a developing country. Objectives: The aim of this study was to search the literature to evaluate the publications that relate the incidence of intraoperative cardiac arrest in Brazil and analyze the trend in the incidence of intraoperative cardiac arrest. Contents: There were 4 articles that met our inclusion criteria, resulting in 204,072 patients undergoing regional or general anesthesia in two tertiary and academic hospitals, totalizing 627 cases of intraoperative cardiac arrest. The mean intraoperative cardiac arrest incidence for the 25 years period was 30.72:10,000 anesthesias. There was a decrease from 39: 10,000 anesthesias to 13:10,000 anesthesias in the analyzed period, with the related lethality from 48.3% to 30.8%. Also, the main causes of anesthesia-related cause of mortality changed from machine malfunction and drug overdose to hypovolemia and respiratory causes. Conclusions: There was a clear reduction in the incidence of intraoperative cardiac arrest in the last 25 years in Brazil. This reduction is seen worldwide and might be a result of multiple factors, including new laws regulating the medicine in Brazil, incorporation of technologies, better human development level of the country, and better patient care.
