Conditions

Postoperative pain control in colorectal surgery is one of the key components for ERAS (Enhanced recovery after surgery) protocol. Inadequate pain control may also lead to postoperative complications such as pulmonary complications, myocardial infarction, ileus as well as transforming into persistent post surgical pain if not controlled. Quadratus Lumborum Block, Elective Open Colorectal Surgery, morphine consumption

Interventions

In QL-group, the block will be performed while the patient is in supine position. A small wedge- shaped pillow will be placed bilaterally behind the patients hip to exposed the posterolateral part of

Primary

MeasureTime frame
cumulative morphine consumption during 24 h postoperatively at 24 hours after patient has arrived at recovery room quantitative measurement (mg)

Secondary

MeasureTime frame
cumulative morphine consumption at PACU, 6,12,48 h postoperatively at 48 hours after patient has arrived at recovery room quantitative measurement (mg),postoperative pain score using numerical rating scale (NRS) at rest and movement at different time point(PACU,6,12,24,48h) at 48 hours after patient has arrived at recovery room numerical rating scale,time until earliest single PCA dose of morphine at 48 hours after patient has arrived at recovery room Norminal scale,side effects associated with the block and morphine used (quadriceps weakness, hematoma, infection, LAST, PONV, itching, and respiratory depression) at 48 hours after patient has arrived at recovery room Norminal scale,quality of recovery after anesthesia measured with the Thai QoR-35 questionnaire at 48 hours after patient has arrived at recovery room ordinal scale,post-operative clinical recovery (time to return of bowel function, time to first oral intake, time to first ambulation, length of in-hospital stay) at 48 hours after patient has arrived at recovery room Norminal scale,patient satisfaction with pain management at 48 hours after patient has arrived at recovery room ordinal scale
