Anesthesia for Vascular Access Devices

The Comparison of Two Different Techniques of Remifentanil Consumption During Implantable Vascular Access Device Procedures

Our aim was to investigate whether remifentanil use in both infusion and bolus techniques could provide sufficient sedation and analgesia without serious adverse effects for central venous access device procedures under monitored anesthesia care.

Study Overview

Detailed Description

The insertion and removal of implantable venous access devices (port-a-cath type) requires moderate level of sedation and monitored anesthesia care to prevent pain and anxiety of patients during the procedure. According to the American Society of Anesthesiologist Physical Status Score, monitored anesthesia care is a planned procedure where a patient undergoes local anesthetic infiltration together with sedation and analgesia. Remifentanil is a potent synthetic opioid with novel pharmacokinetic properties, including very rapid onset and an ultra short duration of action, making it effective for pain relief in short procedures. Remifentanil can be administered as either one of the techniques of intravenous continuous infusion (CI) or intravenous bolus patient-controlled sedation analgesia (PCSA).In previous studies, the insertion or removal of venous access procedures required either local anesthesia or low doses of orally administered anxiolytic medication. The infusion of remifentanil may cause respiratory depression and analgesic efficacy and safety of administration of remifentanil infusion and/or bolus doses of remifentanil during the administration of one of the techniques of either CI or PCSA in short term procedures has not been well studied. The prospective trials that compare analgesic efficacy and adverse events related to intravenous remifentanil consumption in sedation and analgesia of short procedures are very limited.

This study aims to compare level of pain and sedation, total amount of remifentanil consumption, bolus doses of remifentanil, patient and surgeon satisfaction, hemodynamic data and adverse events of two different techniques of intravenous remifentanil use such as; intravenous continuous infusion (CI) or intravenous bolus patient-controlled sedation analgesia (PCSA) in patients under moderate level of sedation for vascular access procedures.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Continuous infusion of remifentanil
In continuous infusion group of patients, remifentanil was infused at a dose of 0.1 µg/kg/min and the additional bolus dose of 0.1 µg/kg was given if required. Before start of the operation, in both groups of patients, intravenous remifentanil at a bolus dose of 0.1 µg/kg was administered slowly in a duration of 60 seconds.
Comparison of numerical pain intensity rating scale Comparison of faces pain rating scale Comparison of consumption of total amount of remifentanil
Other Names:
  • Sedation-Numerical pain intensity rating scale, Faces pain rating scale
  • Analgesia-Ramsey sedation scale
  • Drug-Remifentanil consumption of total amount of remifentanil
Experimental: Patient-controlled sedoanalgesia (PCSA) of remifentanil
In PCSA group of patients, remifentanil was given by bolus PCSA using a pump (Pain Management Provider, Abbott Laboratories and Eczacibasi-Baxter, Ireland). In PCSA group of patients, remifentanil infusion was at a dose of 0.05 µg/kg, a bolus dose of 0.1 μg/kg with a lock-out time of three minutes.

Primary Outcome Measures

Outcome Measure

Time Frame
The Numeric Pain Intensity Rating Scale (NPRS)
Time Frame: After incision and during operative time every five minutes, through the operative time period up to two hours of time.
During NPRS pain evaluation, a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain comparison and this includes 0 as no pain and 10 as the worst pain imaginable. There is a comparison of pain scale scores as a decrease of pain relief in an amount of 30% from the pain at start between the two groups.
After incision and during operative time every five minutes, through the operative time period up to two hours of time.
The faces pain rating scale
Time Frame: After incision and during operative time every five minutes, through the operative time period up to two hours of time.
