Abstract
Sixty male and female ASA class patients (ages 18–70) will provide written informed permission when the study is approved by the institutional ethics council at El-Minia university hospital. Inpatients in Hip Surgery, Levels I and II Each patient was thoroughly assessed for systemic disorders, haematological characteristics, and coagulation profile before any operations were decided upon.
The purpose of this study was to compare the analgesic effects of preoperative ultrasound-guided fascia iliaca blocks on post operative opioid demands, pain scores, and hospital stay in people treated total hip replacement surgery to those of ultrasound-guided, single-shot QL blocks.
Using a computer-generated randomization table, the patients were split into three groups of twenty. Every patient was given a unique identification number (ID) upon admittance to the unit. The patient was assigned to a group using simple randomization in the surgery room using the closed envelope approach. Each patient was given a unique ID at random, and this number was utilised for all postoperative data collection in the hospital ward.
Block group A, or the Quadratus lumborum.
Bupivacaine 0.25%, at a dosage of 0.5 ml./kg, will be used to execute a quaternary level (QL) block.
Block group B, or the Fascia Illiaca.
The bupivacaine 0.25% dosage of 0.5 ml/kg will be used to accomplish the FI block.
group C, the ”control,” received neither the Quadratus Lumborum nor the fascia iliaca blocks.
Each subject was evaluated on the following scales:
1 - Hemodynamic parameters
A) During surgery: • Heart rate (HR), systolic blood pressure (AP), mean arterial pressure (MAP), and blood oxygen saturation (SaO2) were taken before and after spinal anaesthesia, and then 5, 10, 20, 30, 40, 50, 60, and 70 minutes after the block, and then every 15 minutes until the end of the procedure.
• The sum of all opioid and nonopioid pain relievers used during surgery.
B) After surgery: • Vitals at 1, 2, 4, 6, 8, 12, 16, 20, 24 hours for heart rate (HR), mean arterial pressure (MAP), and saline oxygen saturation (SaO2).
• Visual Analog Scale at 1, 2, 4, 6, 8, 12, 16, 20, and 24 Hours After Surgery
When patients initially ask for pain medication.
• The sum of opioid and nonopioid pain relievers used.
• Frequency of adverse events.
When you may expect to leave the hospital’s post-surgery care unit.
Our findings demonstrated that there were no significant differences between the three groups with regard to patient characteristics (age, gender, weight, ASA classification, surgical time, or operation type) or SaO2.
Quadratus lumborum blocks were found to be safe, effective, attenuated the hemodynamic stress response to surgery, reduced the visual analogue scale (VAS) score, postponed the time of first analgesic request, reduced the total amount of postoperative analgesics, shortened the length of hospital stay, and allowed for earlier mobilisation and discharge.
