Brief summary

This study aims to compare the ultrasound-guided bilateral erector spinae plane block (ESPB) and oblique subcostal transverse abdominal plane block (OSTAPB) for postoperative analgesia in colorectal surgery.

Detailed description

Colorectal surgery remains the therapeutic cornerstone for the management of a wide variety of gastrointestinal disorders encompassing malignancies and inflammatory conditions. Oblique subcostal transverse abdominal plane block (OSTAPB) is a regional block technique that involves injecting local anesthetics between the transverse abdominal muscle plane and the internal oblique abdominal muscle plane. Ultrasound-guided erector spinae plane block (ESPB) is a novel technique that specifically targets the ventral rami, dorsal rami, and rami communicantes of the spinal nerves. Local anesthetic agents were observed to extend cranially and caudally over numerous dermatomal levels following injection.

Design outcomes

Primary

MeasureTime frameDescription
Degree of pain24 hours postoperativelyEach patient will be instructed about postoperative pain assessment with the numeric rating scale (NRS). NRS (0 represents "no pain" while 10 represents "the worst pain imaginable"). NRS will be assessed at 0, 2, 4, 6, 12, and 24 h postoperatively.

Secondary

MeasureTime frameDescription
Time to the first rescue analgesia24 hours postoperativelyTime to the first request for the rescue analgesia will be recorded from end of surgery to first dose of morphine administrated.
Intraoperative fentanyl consumptionIntraoperativelyAdditional fentanyl bolus dosages of 1 µg/kg IV will be administered if heart rate or mean arterial blood pressure elevated more than 20% of the baseline (after exclusion of other causes than pain).
Total morphine consumption24 hours postoperativelyRescue analgesia of morphine will be given as 3 mg bolus (maximum dose of 0.5 mg/kg/24hours) if the numeric rating scale (NRS) \> 3 to be repeated after 30 min if pain persists until the NRS \< 4.
Mean arterial pressureTill end of surgery (Up to 2 hours)Mean arterial pressure will be recorded at: * T0: Baseline reading preoperatively (in the preoperative holding area). * T1: Immediately before intubation. * T2: 15 minutes after intubation. * T3: 30 minutes after intubation. * T4: 45 minutes after intubation. * T5: 60 minutes after intubation. * T6: At the end of surgery.
Heart rateTill end of surgery (Up to 2 hours)Heart rate will be recorded at: * T0: Baseline reading preoperatively (in the preoperative holding area). * T1: Immediately before intubation. * T2: 15 minutes after intubation. * T3: 30 minutes after intubation. * T4: 45 minutes after intubation. * T5: 60 minutes after intubation. * T6: At the end of surgery.
Degree of patient satisfaction24 hours postoperativelyDegree of patient satisfaction will be assessed on a 5-point Likert scale patient satisfaction (1, extremely dissatisfied; 2, unsatisfied; 3, neutral; 4, satisfied; 5, extremely satisfied).
Quality of Recovery24 hours postoperativelyQuality of Recovery (QOR- 15) scale will be recorded at 24 hours after surgery. Each item on the QoR-15 scale is scored from 0 (unfavourable) to 10 (favourable), resulting in an aggregate score from 0 (no recovery) to 150 (total recovery).
Incidence of adverse events24 hours postoperativelyIncidence of adverse events such as bradycardia, hypotension, nausea, vomiting, respiratory depression, or any other complication will be recorded.
