Abstract :

Endoscopic third ventriculostomy is a common neuroendoscopic procedure. Bradycardia, tachyarrhythmia, hyperkalemia or hypokalemia may occur during manoeuvring of endoscope, ventricular irrigation, or third ventriculostomy. A prospective, observational study was carried out in 35 patients undergoing neuroendoscopy to find correlation between these changes and anaesthesia technique. Base line preoperative vital parameters, serum electrolytes, details of anaesthesia technique, intravenous fluids, neuroendoscopy, pulse rate, blood pressure, and E.C.G. changes, irrigating fluid, and intraoperative and postoperative serum electrolyte levels were recorded and analysed using Paired students T test. A very highly significant fall in pulse rate was noted during insertion of neuroendoscope (96.29 ± 27.42, p=0.001), 3rd ventriculostomy (96.63 ± 27.079, p=0.000) and removal of scope (93.46 ± 27.91, p=0.000) more so with the use of Fentanyl as analgesic. Hence close communication between the neurosurgeon and the anaesthetist and judicious use of Fentanyl is recommended.
