The goal of this study is to compare the intraoperative hemodynamic status, characteristics of block of fractionated versus single bolus dose of Hyperbaric Bupivacaine in patient undergoing Transurethral Resection of Prostate(TURP) surgery under Subarachnoid block(SAB).
Seventy-two patients aged 50 years and above belonging to American Physical status I and II are divided into two study group.
Group B will receive Injection 0.5 % hyperbaric bupivacaine 2.5 ml single bolus dose and group F will receive same concentration and volume of hyperbaric bupivacaine with two third dose initially (i.e. 1.6 ml) and remaining one third dose (i.e. 0.9 ml) after 60 seconds at the rate of 0.2ml/sec.
The aim of this study is to compare the intraoperative hemodynamic status, characteristics of block of fractionated versus single bolus dose of Hyperbaric Bupivacaine in patient undergoing TURP surgery under SAB.
Seventy-two patients aged 50 years and above belonging to American Physical status I and II undergoing transurethral resection of prostate for benign enlargement of prostate under subarachnoid block are enrolled and are divided into two groups having 36 patients in each.
Group B will receive Injection 0.5 % hyperbaric bupivacaine 2.5 ml single bolus dose and group F will receive same concentration and volume of hyperbaric bupivacaine with two third dose initially (i.e. 1.6 ml) and remaining one third dose (i.e. 0.9 ml) after 60 seconds at the rate of 0.2ml/sec.
Intraoperative mean arterial pressure (MAP), heart rate, onset of sensory and motor block, duration of sensory and motor block, and total intraoperative consumption of vasopressor are observed and compared between the groups.

| Measure | Description | Time Frame |
|---|---|---|
| Comparision of mean arterial pressure(MAP) in both participants with subarachnoid block | Hypotension was defined when mean arterial pressure (MAP) decreased ≤20% from baseline. | Throughout study completion,an average of 3 months |
| Comparision of heart rate in both participants with subarachnoid block | Bradycardia was defined when heart rate is less than 60 beats per minute. | Throughout study completion,an average of 3 months |

| Measure | Description | Time Frame |
|---|---|---|
| Comparision of time for onset of sensory between the groups. | Sensory block was assessed by loss of sensation to pinprick with blunted tip needle bilaterally in the dermatomal levels. It was tested every 3 min until achievement of maximum sensory block i.e. till T10 level | Throughout study completion,an average of 3 months. |

An approval from the Institutional Review Board (IRB), NAMS was taken prior to commencing the study. 72 Patients of ASA physical status I or II scheduled for Transurethral Resection of prostate under Sub-arachnoid block were enrolled in the study. . Patient's characteristics including name, gender, age, body weight, height and body mass index were recorded.
Patients were kept nil per oral as per American society of anesthesiologist guidelines prior to surgery. Study pouplation were divided into two groups:
