Brief summary

The main purpose of this study is to evaluate the postoperative effect of erector spinae block in patients undergoing nephrectomy that causes both visceral and somatic pain.

Detailed description

After being informed and potential risks about the study, all patients have given written consent will undergo 24 hours screening for the analgesic effect of erector spinae block after nephrectomy. Patients meeting the criteria were randomly selected in double-blind manner 1:1 ratio to erector spiane block or not.

Interventions

Administration of local anesthetic under the erector spinae muscle just below the transverse process of the thoracic 12th vertebra

Design outcomes

Primary

MeasureTime frameDescription
Numerical Rating Scale (NRS)24 hoursNumerical Rating Scale (NRS) will be used for postoperative evaluation. NRS is a segmented digital version of the visual analog scale. Selecting an integer (0-10 integers) by a responder in (VAS). It is accepted as one dimensional-the measure of pain intensity in adults. The 11-point numerical scale ranges from 0 to 10, representing a pain (no pain). 10 (as bad pain as you can imagine), or (the worst pain imaginable).

Secondary

MeasureTime frameDescription
Recovery analgesia24 hoursSecondary outcome measures will be routine (paracetamol or tramadol PCA) or recovery. Analgesic use will be recorded within the first 24 hours.
postoperative nausea and vomiting24 hoursThe severity of nausea and vomiting 4-point scale (none, mild, moderate, and severe). As will be recorded by the nurses in the ward.
