Abstract
In day case anesthetic procedures like below knee surgeries, several issues are considered such as safety, procedure time, early ambulation, postoperative analgesia and cost effectiveness. Even though general anesthesia continues to be the anesthetic technique preferred by most of the patients for short procedures, there is some evidence that mortality and morbidity are higher for general anesthesia than for blocks, especially for lower abdominal and lower limb surgeries. Spinal and epidural blocks are relatively simple techniques, however, the risk of complications such as headache, infection, urinary retention, and cardio-circulatory instability are significantly limiting their use in outpatient surgery. Moreover, they are contraindicated in patients with anatomical abnormalities of spine, bleeding disorders and in unwilling patients. Nerve blocks can be useful in such scenarios.
Our study was conducted in Menoufia University Hospitals to study the femoral/sciatic nerve block using ultrasound with and without nerve locator for below knee surgeries. 60 adult patients of both sex scheduled for below knee surgeries with ASA physical status I-IV enrolled in this randomized controlled blinded prospective clinical trial study and were divided into two groups according to type of anesthesia used:
group A – femoral and sciatic nerve block using ultrasound only
group B – femoral and sciatic nerve block using ultrasound combined with nerve locator.
