Overview

To determine the effectiveness of saddle block vs spinal anesthesia in TURP.

This study is being conducted to determine the effectiveness of saddle block vs spinal anesthesia in terms of haemodynamic stability and Vasopressor usage.

Interventions

0.5% Hyperbaric BupivacaineDRUG

In both groups 0.5% Hyperbaric Bupivacaine is given intrathecally and then saddle group is advised to stay in sitting position for next 5minutes so that drug can block only lower segments of nerves, Lumber 5th to Sacral dermatomes level. The spinal group is advised to take supine position immediately so that drug distribution be uniform uptill T10 level of spinal dermatome. Then outcomes regarding haemodynamic status and vasopressor usage are recorded

Outcomes

Primary Outcomes

Haemodynamic status

Haemodynamic status includes pulse rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure and oxygen saturation. Pulse rate ranges between 60-100 beats/ minute. Pulse above 100 is called tachycardia and below 60 is called bradycardia Systolic blood pressure more than 140mmhg is called systolic hypertension and lower than 90mmhg is known as systolic hypotension. Diastolic blood pressure more than 90mmhg is called diastolic hypertension and lower than 60mmhg is called diastolic hypotension. Mean arterial pressure ranges between 70-110. More than 110 labeled as hypertension and below 70 means hypotension. Spo2 level below 94% is labeled as hypoxia.

Time frame: Haemodynamic status checked from 0minutes ( as the patient takes supine position) for every 5minutes interval till the end of surgery.

Vasopressor usage

The main side effect of intrathecal 0.5 % hyperbaric Bupivacaine is hypotension. That is countered by using vasopressor drug e.g inj. Ephedrine. Critically low blood pressure e.g systolic bp below 90mmhg, diastole c blood pressure below 60mmh and MAP below 60 is an indication for vasopressor introduction.

Time frame: Blood pressure is taken from 0minute (as the patient takes supine position) at every ⁵minutes interval till the end of surgery
