Abstract

Background:

Ultrasound guided sciatic nerve block has been proved to be effective in pain control for lower limb surgeries, fortunately, it can be performed at different levels via different approaches.

Aims:

To compare the effectiveness of the sub-gluteal and the popliteal approaches of blocking the sciatic nerve as well as their success rate.

Settings and Design:

After approval of the ethical committee and obtaining a written informed consent from 56 ASA II, III patients aged 45–75 year, this prospective, randomized, interventional double blinded study was done to patients undergoing elective below knee amputation.

Methods:

Patients were randomly assigned to receive either sciatic nerve block using a popliteal approach (group P, n 28) or a sub gluteal approach (group G, n 28). femoral nerve block done for sensory block of the medial side of the leg. Time to complete sensory and motor block, time taken to perform the block, block-related complications, block duration, time for asking for rescue analgesia in the first 24 h and both patients′ and surgeons′ level of satisfaction were recorded. Success of the block was considered when the block is solid and doesn’t require shifting to GA.

Result:

Patients in the P group had a 100% success rate, shorter time to perform the block, less overall complications, required no postoperative rescue analgesia. Yet, more surgeons preferred the sub-gluteal approach.

Conclusion:

Popliteal approach is as effective as the sub-gluteal approach block providing adequate analgesia with a 100% success rate

Keywords: Below knee amputation, Femoral nerve block, Popliteal nerve block, Sciatic nerve block, Sub-gluteal, Ultrasound guided.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."
