Comparison of Effects between Combined Lumbar-Sacral Plexus Block plus General Anesthesia and Unilateral Spinal Anesthesia in Elderly Patients Undergoing Hip Fracture Surgery: A Pilot Randomized Controlled Trial

Purpose. Hip fracture is a common injury in geriatric populations, which is associated with poor quality of life. However, the ideal anesthesia technique for this disease is yet to be identified. This study aimed to compare the combined lumbar-sacral plexus block (CLSB) plus general anesthesia (bispectral index (BIS) 60–80) with the unilateral spinal anesthesia (SA) on activity of daily living in elderly patients undergoing hip fracture surgery. Methods. A total of 124 elderly patients undergoing hip fracture surgery were randomly assigned to two groups. Patients in the SA group received light-specific gravity spinal anesthesia, and patients in the CLSB group received lumbar and sacral plexus block with general anesthesia (BIS 60–80). The primary outcomes were 30-day activity of daily living (ADL). The secondary outcomes were postoperative pain scores, postoperative delirium, in-hospital cost, and major complications. Results. The ADL scores of postoperative day 30 (POD30) in the CLSB group are higher than those in the SA group (27.34 ± 7.01 versus 24.70 ± 6.40, P = 0.045 ). Compared to preoperative ADL scores, there were higher increased scores in the CLSB group than in POD30 (CLSB group 8.09 ± 3.39 versus SA group 4.87 ± 3.90, P < 0.001 ). Mild-to-moderate pain did not have differences between the two groups (rest pain: 3 versus 2, P = 0.344 ; motion pain: 5 versus 4, P = 0.073 ). There were no significant differences in incidence of postoperative delirium, PONV, and other complications. Conclusion. The unilateral SA can reduce the deterioration of ADL after hip fracture surgery and provide a better postoperative recovery.

Comparison of Various Techniques of Anesthesia for Surgical Management of Diabetic Foot

Background: Diabetes mellitus is a multisystem disease caused by an absolute or relative deficiency of insulin secretion or resistance or a combination of both. Anesthesia in them is of special concern because of complex polypharmacy, an inappropriate dose of oral hypoglycemic agents or insulin and errors in converting IV insulin to usual medication. The objective is to compare the various techniques of anesthesia for surgical management of diabetic foot in terms of intraoperative hemodynamic stability, perioperative problems related to anesthesia techniques, postoperative analgesia. Subjects and Methods: Sixty adult diabetic patients of both gender of ASA grade II-III, aged 35years undergoing surgical management of diabetic foot were elected and separated into three groups, Group A: general anesthesia with tracheal intubation, Group B: unilateral spinal anesthesia with injection 0.5% bupivacaine heavy 1.5ml (7.5mg), Group C: popliteal nerve block via lateral approach by injecting 30 ml 0.5% bupivacaine. Parameters like pulse rate, mean arterial blood pressure, respiratory rate and SpO2 were recorded at regular intervals. Postoperative pain, perioperative side effects, complications and problems related to anesthetic techniques were noted. The analysis is done by unpaired t-test and chi-square test. Results: Group C patients were hemodynamic stable than Group A and B. Post-op analgesia was prolonged in Group C. Perioperative side effects were more found in Group A. Conclusion: Popliteal nerve block and unilateral spinal anesthesia provide better hemodynamic stability and postoperative analgesia with negligible side effects as compared to general anesthesia for surgical management of diabetic foot.

Anesthesia For Total Arthroplasty Of The Joints Of The Lower Extremities In Patients With A High Anesthetic Risk

Purpose: to determine the effect of unilateral spinal anesthesia on systemic and central hemodynamics, to identify its side effects in the elderly and senile, with total hip replacement. Materials and methods: 60 patients of geriatric age operated on under unilateral spinal anesthesia were examined. 44 patients underwent total hip arthroplasty (THA), 16 - total knee arthroplasty (TKA). Inclusion criteria: elderly (from 60 to 75 years). For continuous monitoring of the vital functions of the patient, they used the "resuscitation and surgical" monitor UM 300 (LLC UTAS Company Ukraine). Conclusion: Unilateral spinal anesthesia is a safe and highly effective technique that can provide full intraoperative pain management for patients with total hip replacement in a high-risk group of patients.

The effectiveness of using self-made hyperbaric solution of bupivacaine for unilateral spinal anesthesia

The main idea of this research was to determine the effectiveness of holding the unilateral spinal anesthesia in comparison with total, positive and negative effects of these manipulations. In Ukrainian medical practice, the technique of spinal anesthesia for analgesia of surgical interventions on the abdominal cavity and lower extremities has been introduced for a long time. One of the main methods is unilateral spinal anesthesia. The study compared: the effectiveness of anesthesia, the duration of anesthesia, the volume of infusion therapy during surgery and the reaction of the cardiovascular system to the manipulations.

UNILATERAL SPINAL BLOCK FORMATION BY TACHYPHYLAXIS METHOD

The article presents the theoretical justification and comparative experience in the formation of a unilateral spinal block by tachyphylaxis in urgent surgery during operations on the lower extremities. The possibility of influencing the duration and severity of motor blockade on the operated side was established using the tachyphylaxis method for administering the anesthetic without decreasing the quality of anesthesia as a whole and without increasing the amount of anesthetic administered. The possibility of reducing the development time of full anesthesia to a minimum fixation time of anesthetic on nerve tissue (10 minutes) due to preliminary «sensitization» to nerve fiber anesthetics was established. The possibility of reducing the need for postoperative analgesia by increasing the duration of the postoperative painless period has been established. Keywords: unilateral spinal anesthesia, frequency-dependent blockade, motor block.
