"For central venous access device procedures under monitored anesthesia care, remifentanil use in both infusion and bolus techniques could provide sufficient sedation and analgesia without serious adverse effects" Sagiroglu et al (2021).

Sedation for CVC insertion

Abstract:

Purpose: The aim was to compare analgesic efficacy and adverse effects of two different techniques of intravenous remifentanil administration in patients undergoing vascular; access device procedures with monitored anesthesia care.

Design: A randomized, single-blinded controlled study.

Methods: The patients (N = 92) were 30-80 years old and of American Society of Anesthesiologists Physical Status I-III. The first group was the continuous infusion group (group CI). Intravenous continuous remifentanil was infused after starting at a dosage of 0.1 mcg/kg/min, and the dose was raised incrementally up to 1 mcg/kg/min if required. The second group was intravenous bolus patient-controlled sedation analgesia (PCSA) with remifentanil infusion at a dose of 0.05 mcg/kg per minute and bolus of 0.1 mcg/kg with lock-out time of 3 minutes. In both groups, a bolus dose of 0.1 mcg/kg remifentanil was administered. The data evaluated include level of pain and sedation, total amount of remifentanil consumption, bolus doses of remifentanil, patient and surgeon satisfaction, hemodynamic data, and adverse events.

Findings: In comparison between techniques, pain and sedation scores during procedure, duration of procedure, patient and surgeon satisfaction, additional rescue medication, and bolus doses were not statistically different (P > .05). The total amount of remifentanil administered was significantly lower in the infusion group than that in the bolus group (P = .031).

Conclusions: For central venous access device procedures under monitored anesthesia care, remifentanil use in both infusion and bolus techniques could provide sufficient sedation and analgesia without serious adverse effects. Total remifentanil consumption amount in infusion group is lower than that in the bolus group.
