Opioid-free anesthesia for minimally invasive abdominal surgery: a systematic review, meta-analysis, and trial sequential analysis.

Purpose: Opioid anesthesia is commonly employed in minimally invasive surgeries but is associated with adverse effects, including postoperative nausea and vomiting (PONV). Opioid-free anesthesia aims to mitigate these issues. We conducted a systematic review, meta-analysis, and trial sequential analysis (TSA) comparing opioid and opioid-free anesthesia in minimally invasive abdominal surgeries.

Erector spinae plane block versus intravenous opioid for analgesia in pediatric cardiac surgery: A systematic review and meta-analysis.

Introduction: The erector spinae plane block (ESPB) has recently emerged as a regional anesthesia technique for perioperative pain management in pediatric cardiac surgery. However, evidence comparing its effectiveness with intravenous (IV) opioid-based analgesia is limited. We aimed to evaluate and compare the analgesic efficacy of ESPB versus IV opioids in this setting.

Intraoperative and immediate postoperative transfusion: Clinical-hematological profile of transfunded patients in a university hospital.

Introduction: The transfusion practice by surgery blood reserve, varied among services, must be performed through the rational and restrictive use of blood components because it is a scarce and expensive resource for health care services.

Objective: Analyze the use of blood products for surgery blood reserve by means of the study of the clinical-hematological profile of patients submitted to intraoperative and immediate postoperative transfusions.

Methods: This was an observational, cross-sectional, and retrospective study, conducted by collecting biological, operational, and laboratory variables, involving 680 patients at a university hospital who had elective surgery with surgery blood reserve request sent during the period from October 2021 to October 2022.
