Abstract
Objectives: We aimed to retrospectively investigate the efficacy of ultrasound guided rectus sheath block (RSB) method in our study.
Methods: We scanned 235 patient files operated for abdominal pathology. Patients meeting the criteria were evaluated for intra-operative rectus sheath block and two different groups were formed. In these two groups of patients visual analogue scale (VAS) values recorded from the postoperative pain follow-up form and analgesic delivery (DEL) and analgesic demand (DEM) values recorded from patient controlled analgesia (PCA) device were compared. In addition, complaints of nausea, vomiting and constipation were evaluated.
Results: Postoperative VAS values (Postoperative 1, 12 and 24 hours p<0.001), DEM values (Postoperative 1, 12 and 24 hours p<0.001) and total amount of morphine consumed (Postoperative 1, 12 and 24 hours p<0.001) were lower in patients with RSB. Also, in patients with RSB nausea (p=0.014) and vomiting was less seen postoperatively (p=0.007). In the first 24 hours after surgery, constipation was seen in 8 patients with RSB and constipation was seen in 30 patients without RSB (p=0.00).
Conclusion: Ultrasound guided rectus sheath block is an effective method for postoperative pain control.
