Background: Spinal anaesthesia consists of inserting a spinal needle into the subarachnoid space and, when a free flow of cerebrospinal fluid (CSF) is obtained, injection of a solution of local anaesthetic directly into the CSF. In Paediatric Patients Spinal Anaesthesia is used for subumbilical surgeries but still there is a concern about its safety & feasibility. Objective: To assess the spinal anaesthesia in paediatric patients of district level hospital, Tangail, Bangladesh. Materials and Methods: In this prospective study was conducted in the Dept. of Anaesthesia, Sheikh Hasina Medical College Hospital, Tangail, Bangladesh from January to June 2021. 32 paediatric patients of aged 2-10 years were included undergoing sub umbilical surgery. Under all aseptic precautions and sedation, subarachnoid block was given with 27g quineke needle through L3-L4 or L4-L5 subarachnoid space & hyperbaric 0.5%. Bupivacaine was administered according to the weight of children. The dose of Bupivacaine used was 0.1ml\kg for child (<5kg), 0.08ml\kg (5-15kg), 0.06ml\kg (>15kg). Demographic data, vital parameters, sensory –motor block characteristics & complications were noted. Results: The mean and standard deviation of age is 5.17+2.83 (2-10) years and Mean Weight (Kg) 15.23+7.43 (7.8-23). Out of the 32 cases, 24 were males whereas the remaining 8 were females. In this study indication of high perception RIH 10 (31.25%), Fracture shaft of femur 4 (12.5%), LIH 4 (12.5%), Umbilical Polyp 2 (6.25%), Distal Hypospadias 5 (15.62%), Re-Circumcision 2 (6.25%), Undescended testicle 3 (9.37%), Appendicitis 1 (3.12%) and Mucous Cyst 1 (3.12%). In our study common SA Herniotomy 14 (43.75%), Circumcision 2 (6.25%), Urethroplasty 5(15.62%), Excision polyp 2(6.25%), Orchiopexy 3(9.37%), Ortho surgery 4 (12.5%), Mucous Cyst Excision 1 (3.12%). There was no significant change in vital parameters. Mean peak sensory level was T 6.20 ±1.20 (T4- T8). Mean sensory level at the end of surgery was T8.11±1.4
