Design: The study on PDPH was conducted as comparative and prospective. Study comparing thetwo different spinal needles of 25 G and 27 G (different calibers for incidence of Post dural puncture headache). Placeof study: This study was conducted in Anaesthesiology department CMH Lahore.. Patients and methods: For thisstudy the literature from different books/magazines/ journals and internet was consulted to make the study comparable.The study design contained the patients selection through randomization technique. Proper criteria for selection of thepatients were opted and in it only A.S.A.1 Patients were studied. Similarly certain specific age group (young patients)were kept for this study to get accurate results, proper caparison and patients and already got spinal anaesthesia werenot tested too. Quincke Babcock spinal needles of 25G and 27G were easily available in the market. This clinical trialcontained eighty patients divided in two groups. After taking all precautionary measures they were given spinalanaesthesia and after it they were observed for spinal headache (study performa annexed). Epidural blood patcheswere also given in those patients who were given spinal anaesthesia with 25G needle, where required. Conclusion:The results of the study were tested by use of Chi¡¯s square test with 1/ of freedom. The results confirmed thehypothesis that smaller caliber needle (27G) caused no PDPH while bigger caliber needle (25G) caused headache inpercentage of patients. In the end the references from the concerned literature were cited and results were foundcomparable as given in the literature. The role of smaller caliber needles was well evaluated in this study. %K spinal Anaesthesia %K epidural blood patch %K post-dural puncture headache %U http://www.theprofesional.com/v14n3/prof-1182.pdf
