RESUMO
Background Opioids have long been the cornerstone of drugs used for perioperative analgesia. Sufentanil has an advantageous pharmacological profile for its use in continuous intravenous (IV) infusion, yet remains poorly described. Our institution has implemented analgesia protocols with IV sufentanil infusions for cancer surgery with appropriate monitoring. The aim of this study was to evaluate the efficacy and safety of IV sufentanil infusion. Methods A single-center retrospective cohort study was conducted through the analysis of patients' records and the acute pain service database. Inclusion criteria were adult patients admitted for elective cancer surgery and with postoperative IV sufentanil infusion during one year period. Descriptive and inferential statistical analysis was performed by using Software SPSS Statistics (IBM Corp., Armonk USA): Kruskal-Wallis, Mann-Whitney, Chi-square and Fisher tests; Bonferroni chi-square residual analysis, binary logistic regression; p<0.05. Results The study population of 304 patients had a median age of 66 years (22-91) and 229 (75.3%) were men. 38 (12.5%) were chronic opioid users. Head and neck/otorhinolaryngology (ORL) surgery was performed in 155 (51.0%) and abdominopelvic surgery in 123 (40.5%). The median days of IV sufentanil infusion were 2 (1-13). At rest and with movement, analgesia was considered good, i.e., over 90% of patients with visual analogue scale (VAS) pain score ≤ 3. We found that patients submitted to musculoskeletal surgery had higher VAS pain scores; this group also presented older patients with higher American Society of Anesthesiologists (ASA) physical status classification and more chronic opioid users (p<0.05). 144 patients (47.4%) had at least one adverse effect related to IV sufentanil infusion, notably transient and not requiring any specific treatment. These patients were older and had longer infusion periods (p<0.05). 237 (98.3%) of the adverse effects occurred during the first 3 days and the most common were: sedation (n=104, 42.8%), hypotension (n=32, 13.2%), hypoxemia (n=31, 12.8%) and nausea/vomiting (n=25, 10.3%). The reported incidence of respiratory depression was 2.9% (n=9), with three patients (1%) requiring advanced treatment. Conclusion Multimodal analgesic protocols with IV sufentanil infusions provided good postoperative analgesia for head and neck/ORL and abdominopelvic cancer surgeries. The adverse effects associated with the IV sufentanil infusions were mild and mainly managed with opioid dose reductions. Our study showed that this approach can be a safe option for postoperative multimodal analgesia in cancer surgery with appropriate monitoring in high-dependency units.
RESUMO
Background Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) is an effective treatment option for appropriately selected patients with peritoneal carcinomatosis. Our aim was to analyze a multidisciplinary approach and to study the perioperative risk factors associated with morbidity and mortality. Methods We reviewed all patients who underwent CRS + HIPEC from January 2019 till December 2020 at our oncologic center. Patient demographics, risk scores, intraoperative variables, postoperative care, analgesia protocol, and adverse events (AE) within 30 days after treatment were collected and statistically analyzed. Results Of the 98 patients evaluated preoperatively by a multidisciplinary team, 39 patients required active optimization. The median age was 61 years, and 67 were women. Most tumors were appendiceal in origin. The median peritoneal cancer index (PCI) score was 12, and the median operative time length (OTL) was 400 minutes. Body mass index, Physiological and Operative Severity Score for the enUmeration of morbidity, PCI score, crystalloid volume, cell concentrates, and OTL were associated with postoperative intensive care unit admission (p <0.05). Epidural analgesia was given to 74 patients. AEs occurred in 39 patients, and 25 of the AEs were classified as mild or moderate. The intraoperative variables associated with development of AEs were anesthesia technique, estimated blood loss, crystalloid volume, cell concentrates, OTL, and analgesia protocol (p <0.05). On multivariate analysis, crystalloid volume >6 L, intravenous sufentanil analgesic protocol, and OTL were associated with 67%, 38%, and 15% increased risk of AE, respectively. Conclusion Our study highlighted the importance of a perioperative protocol with a standardized multidisciplinary approach in order to decrease the incidence of postoperative AE.
RESUMO
Highly active antiretroviral therapy (HAART) has created a new paradigm for human immunodeficiency virus (HIV)-infected patients, but their increased risk for coronary disease is well documented. We present the case of a 57-year-old man, co-infected with HIV-2 and hepatitis B virus, adequately controlled and with insulin-treated type 2 diabetes and dyslipidemia, who was admitted with non-ST elevation acute myocardial infarction. Coronary angiography performed on day four of hospital stay documented two-vessel disease (mid segment of the right coronary artery [RCA, 90% stenosis] and the first marginal). Two drug-eluting stents were successfully implanted. The patient was discharged under dual antiplatelet therapy (aspirin 100 mg/day and clopidogrel 75 mg/day) and standard coronary artery disease medication. He was admitted to the emergency room four hours after discharge with chest pain radiating to the left arm and inferior ST-segment elevation myocardial infarction was diagnosed. Coronary angiography was performed within one hour and documented thrombosis of both stents. Optical coherence tomography revealed good apposition of the stent in the RCA, with intrastent thrombus. Angioplasty was performed, with a good outcome. The acute stent thrombosis might be explained by the thrombotic potential of HIV infection and diabetes. There are no specific guidelines regarding HAART in secondary prevention of acute coronary syndromes. A multidisciplinary approach is essential for optimal management of these patients.
