Sedation Methods in Percutaneous Transhepatic Biliary Drainage: Procedure Quality and Recovery

2026年6月8日 更新者:Ankara City Hospital Bilkent

Evaluation of Sedation Methods Used in Percutaneous Transhepatic Biliary Drainage Procedures in Terms of Procedure Quality, Recovery Time, and Side Effects

This prospective, randomized, single-center study aims to evaluate and compare two different sedation and analgesia regimens used during percutaneous transhepatic biliary drainage (PTBD) procedures. A total of 96 adult patients undergoing elective PTBD or biliary stenting will be randomized to receive either propofol-remifentanil or propofol-ketamine sedation. The primary outcome is recovery time assessed using the Modified Aldrete Score. Secondary outcomes include procedure quality, pain scores, patient and operator satisfaction, hemodynamic stability, and the incidence of sedation-related adverse events. The study is designed to determine the optimal sedation strategy for PTBD, particularly in fragile and elderly patient populations.

調査の概要

詳細な説明

Percutaneous transhepatic biliary drainage (PTBD) is a therapeutic procedure commonly performed in patients with biliary obstruction when surgical intervention or endoscopic retrograde cholangiopancreatography is not feasible. These patients frequently present with advanced age, malignancy, cholangitis, and significant comorbidities, making them particularly vulnerable to sedation-related complications.

Procedural sedation and analgesia are commonly used during interventional radiology procedures to ensure patient comfort, immobility, and procedural success. However, inadequate sedation may result in patient movement, increased anxiety, procedural failure, and complications, whereas excessive sedation may lead to hemodynamic instability, respiratory depression, and delayed recovery, especially in frail patients.

In this study, two commonly used sedation regimens-propofol combined with remifentanil and propofol combined with ketamine-will be compared. Both regimens are routinely used in non-operating room anesthesia settings in our institution. Patients will be randomly assigned in a 1:1 ratio to one of the two groups. Standard monitoring will be applied, including non-invasive blood pressure, electrocardiography, and pulse oximetry, with supplemental oxygen administered via nasal cannula.

Sedation depth will be targeted to a Ramsay Sedation Score of 3-4 and assessed every five minutes during the procedure. Hemodynamic parameters, oxygen saturation, pain scores, recovery time, and adverse events such as hypotension, bradycardia, hypoxia, nausea, vomiting, and airway interventions will be recorded. Recovery will be evaluated using the Modified Aldrete Score at two-minute intervals until adequate recovery is achieved.

The primary objective of the study is to compare recovery times between the two sedation regimens. Secondary objectives include comparison of pain intensity, patient and operator satisfaction, total drug consumption, procedural tolerance, and incidence of adverse events. The findings of this study aim to contribute to safer and more effective sedation strategies for PTBD procedures in high-risk patient populations.

介入・治療
実験的:Propofol-Remifentanil
Participants received intravenous propofol 0.5 mg/kg followed by a continuous intravenous remifentanil infusion initiated at 0.10-0.18 mcg/kg/min during the procedure. The remifentanil infusion rate was adjusted within the specified range according to clinical response to maintain adequate sedation, analgesia, and hemodynamic stability throughout the procedure.

実験的:Propofol-Ketamine
IParticipants received intravenous propofol 0.5 mg/kg followed by intravenous ketamine 0.3 mg/kg. Additional intravenous ketamine 5 mg was administered every 5 minutes as needed during the procedure to maintain the target sedation level and hemodynamic stability.
