Comparison of classical midline approach versus modified paramedian approach in spinal Anaesthesia for lower limb orthopedic surgeries in elderly patients

After approval from ethical committee, patients posted for lower limb orthopedic surgeries in geriatric age from the Department of Orthopaedics surgery will be taken for study after obtaining written and informed consent, anaesthetic checkup will be done on those patients who fit into the inclusion criteria will be analyzed thoroughly and taken up for the study.

Randomization will be done by computer generated card of patient and allocated into two equal groups: Group A and Group B

Group A: Patients who are receiving classical midline neuraxial block (n=40)

Group B: Patients who are receiving modified paramedian neuraxial block (n=40)

During the procedure, number of attempts, time taken to perform the spinal anaesthesia will be recorded. After the procedure, standard monitoring of ECG, pulse oximetry and non-invasive blood pressure for 30minutes.

After adequate eye opening and maintenance of airway reflexes patients would be transferred post anesthesia recovery unit. All patients are followed up by postoperatively for 24 hours.

Further patients will be assessed for the efficacy of post operative analgesia using the VAS score and will be monitored for other variables such as complications.
