Comparison of Paramedian with Midline technique of Spinal Anaesthesia in elderly

Objective: To compare the technique of paramedian with midline approach of subarachnoid block in terms of number of attempts and frequency of success rate in elderly patients undergoing elective lower body surgeries

Study Design: Randomized controlled trial

Place and Duration of Study: This study was carried out at Anaesthesia department of Combined Military Hospital Lahore. Six months from Jan 2014 to Jun 2014

Material and Methods: One hundred and seventy elderly patients were scheduled for lower body surgery, using spinal anaesthesia. They were randomized to either Midline approach [n=85] or Paramedian approach [n=85] by lottery method. The outcome measures number of attempts and success rate were noted in both groups and analyzed using SPSS version 18

Results: The successful block in first attempt was 95.3 percent in Paramedian group and 58.8 percent in Midline group. Mean number of attempts in paramedian group was 1.24 +/- 0.52 as compared to 1.95 +/- 0.97 in midline group. A p-value <0.05 was taken significant

Conclusion: The Paramedian technique was found associated with higher success rate, lesser possibility of repeated number of attempts in elderly patients as compared to Midline approach

Comparison between angiographic findings of the coronary artrey involved in acute myocardial infarction between military and civilian sectors

Objective: Comparison between involvement of different coronary arteries in acute myocardial infarction among military and civilian population

Place: Combined military hospital Lahore and Punjab institute of cardiology Lahore

Time Duration: From 15th March to 15th April 2010

Study Design: Comparative cross-sectional study

Patients And Methods: 50 civilians patients admitted in PIC Lahore and 50 patients admitted in CMH Lahore with confirmed acute myocardial infarction on angiography were selected in the study by consecutive sampling

Results: Involvement of left circumflex coronary artery was documented only in military personnel [p=.003], whereas left anterior descending artery was predominantly [64%] involved in civilian population [p=.091]. Military personnel had more [42%] triple vessel coronary artery disease [p=.003] and double vessel coronary artery disease [p= 0.001] in contrast to civilian population

Conclusion: Involvement of coronary arteries varies significantly [p=.000] among the different sectors of the same society
