Background: Hypotension and bradycardia after conduction of spinal anaesthesia are common side effects because sympathetic blockade. Efforts to prevent these complications have been attempted like preloading with crystalloids, colloids or use vasopressors. The role volume haemodynamic changes associated has recently questioned. Objective: objective the study was investigate preload on patient's hemodynamic. Materials methods: A Quasi- experimental design used conduct study. Taking written informed consent, 40 patients age group 18-45 years ASA grade I II undergoing surgery under in operation theatre Dhulikhel Hospital were selected as sample allocated randomly 2 groups. Group did not receive received 1000 ml Ringer's lactate solution within 30 minutes immediately before giving anaesthesia. An observational checklist collect demographic, intraoperative post-operative records systolic blood pressure (SBP), diastolic (DBP), mean arterial (MAP) heart rate (HR). Results: findings revealed that occurred all patients. decrease SBP, MBP DBP from baseline statistically significant at points time (p=0.000).

There no differences Conclusion: On basis findings, it is concluded had effect Key words: Preload; Haemodynamics; Spinal Anaesthesia; Crystalloid DOI: 10.3126/kumj.v8i2.3562 Kathmandu University Medical Journal (2010), Vol. 8, No. 2, Issue 30, 216-221
