Cardiac IED Implantation Clinical Trial
Official title:
A Randomized, Controlled Trial on Patients Undergoing Cardiac Implantable Electronic Device Implantation With Local Anaesthesia and Sedation With and Without Pectoral Nerve Block
Implantation of cardiac implantable electronic devices are generally carried out using
intermittent intravenous conscious sedation combined with local anaesthesia. The main
advantage of this technique is in avoiding the potential risks of general anaesthesia.
However, the use of this Sedation - Local Anaesthesia technique is not without complications.
Peri -procedural hypoxaemia and hypotension are well recognised complications of this
technique.
The pectoral nerves (Pecs) blocks are novel techniques to block the pectoral,
intercostobrachial, third to sixth intercostals, and the long thoracic nerves. PECS block
targets the lateral and median pectoral nerves at an interfascial plane between the
pectoralis major and minor muscles.
A case report by Fujiwara et al has described the use of this technique to provide good
analgesia during and after these implantation procedures surgery. Pectoral nerves block along
with minimal sedation has been used as a safe technique in our local set up as well.
Hence, we propose a randomized, single center, controlled trial on patients undergoing
cardiac implantable electronic device implantation with local anaesthesia and sedation with
and without Pectoral Nerve Block.
Intervention group:
Pectoral nerve block will be performed by anaesthetist (not blinded) in cardiac
catheterization laboratory using ultrasound guidance and strict aseptic technique.
Control group:
A sham "block" will be performed by anaesthetist in cardiac catheterization laboratory using
strict aseptic technique.
Patients of both groups will be monitored by the Cardiologist ( performing the procedure) and
the Nurse from the monitoring room.
A minimum period of 15 minutes will be allowed following the block, prior to device
implantation procedure by cardiologist.
Numeric rating scale (NRS) will be used for assessment of pain. The assessment will be
carried out at every 15 minutes from the start of the procedure till the end of the procedure
(0, 15, 30, 45, 60 minutes etc) and also at specific time points. Numerical rating scale will
also be assessed when the patient experiences pain at any point and in the recovery room (0,
15, 30 and if needed, 45, 60 minutes).
Further post-operative pain scores will be collected at 4 hours and 8 hours post-procedure.
