The estimation of Depth from Skin to Subarachnoid Space (DSS) may be helpful in selecting the appropriate length of the spinal needle before insertion and decrease the chances of accidental dural puncture. Aim: To determine the usefulness of previously suggested formulae and to derive mathematical formulae to predict DSS for the Indian population. Materials and Methods: After approval from the Institutional Ethics Committee, 700 American Society of Anaesthesiologists (ASA) Physical Status I and II patients were recruited from August 2017 to July 2018. Patients of either sex in the age group of 18-65 years, undergoing elective surgeries under spinal anaesthesia were included in this cross-sectional study. DSS was measured after Sub Arachnoid Block (SAB) and it was compared with various formula-based predicted DSS. Multivariate regression analysis was done to evaluate the influence of anthropometric indices on DSS and formulae were derived for the Indian population. p WHR>Weight>WC>Height in decreasing order. DSS correlates best with Body Mass Index (BMI) and WHR. Conclusion: The proposed formulae based on BMI can be used to predict the DSS. It would help in the selection of appropriately sized spinal needle which in turn would reduce the number of attempts and incidence of failure and complications in patients.
