Study of Pain, Nausea, and Complications After Gallbladder Surgery Using Swedish National Registry Data

What this Trial Is About

Researchers are evaluating data from Swedish national registries to study the occurrence of pain and postoperative nausea and vomiting PONV after gallbladder surgery. The study aims to understand factors linked to higher risks of PONV and pain, including patient characteristics and surgical details. It also explores whether different anesthesia types and regional blocks affect these outcomes and the risk of complications up to six months after surgery. This observational study uses linked data from the Gallriks registry for gallbladder surgeries and the Swedish Perioperative Register SPOR, which records detailed perioperative and postoperative information. Data include patient health, surgery details, anesthesia, pain scores, nausea, and complications. The study includes patients who had gallbladder surgery between 2016 and 2025, with data updated yearly. The study database will analyze thousands of cases, focusing on early postoperative pain and nausea during the average 3.5-hour stay in the post-anesthesia care unit PACU. Participants involvement is through the collection and analysis of registry data with no direct interventions. Researchers will assess pain scores, nausea occurrence, and complications up to six months post-surgery. The study uses descriptive and statistical analyses to identify associations between patient or surgical factors and outcomes. Personal data are pseudonymized to protect privacy. The study period covers surgeries over ten years, allowing comprehensive long-term evaluation.
