Dr. Sagar R. Chavan, Dr Sneha H. Sathe

Abstract :

Introduction: Smoking tobacco can lead to delay in impulse conduction of nerves. Nerve conduction latency is a vital parameter in nerve conduction study. The present study was undertaken to assess median nerve conduction latency in male smokers

Objectives: To study median nerve conduction latency in healthy male smokers and compå it with age, BMI matched non–smokers.

Material and Methods: Study was carried out in 120 subjects belonging to age group 25–45 years. Sensory and motor nerve conduction latency was tested in median nerve by standard method in healthy male smokers, who were subdivided according to smoking index into mild, moderate and heavy smokers group (30 subjects/group). Control group had 30 age & BMI matched non–smokers. Mean value of nerve conduction latency of different groups was compared statistically by one way Anova test and Bonferroni’s test.

Results: The difference in mean values of nerve conduction latency (m/sec) in median sensory nerve of smokers was statistically significant among all the compared groups. The difference in mean values of nerve conduction latency (m/sec) in median motor nerve was statistically non–significant among all the compared groups.

A significant positive correlation was observed between smoking index and median sensory nerve conduction latency. A non–significant correlation was observed between smoking index and median motor nerve conduction latency.

Conclusion: Smoking increases nerve conduction latency in median sensory nerve while it does not significantly affect nerve conduction latency in median motor nerve in apparently healthy smokers.
