Brief Summary

Colorectal cancer is the third most common cancer worldwide. These patients usually undergo open surgical resection of cancer under general anaesthesia.

The aim of this study is to detect whether the Erector spinae plan block or Quadratus lumborum block will provide the most ideal analgesia for these patients. Erector spinae plan block is a novel analgesic technique that provides both visceral and somatic analgesia due to its communication with the paravertebral space. Quadratus lumborum block is a truncal nerve block usually used for intra-abdominal surgeries. Ultrasound guidance increases the accuracy and safety of both techniques. A local anaesthetic mixture of Bupivacaine 0.25% and dexamethasone will be used for both techniques.

Detailed Description

Erector spinae plane block and quadratus lumborum block are analgesic techniques suitable for open colorectal cancer surgeries. postoperative pain score, serum levels of biomarkers of stress (cortisol and CRP), primary hemodynamics, time to first rescue analgesic request, the total amount of rescue analgesic consumption and postoperative nausea and vomiting are the parameters of comparison between both techniques.

Primary Outcome Measures
NameTimeMethod
Postoperative pain scoreFrom 1 day before the surgery to the 2 days after surgery

The intensity of pain indicated by a segmented numeric scale in which a respondent selects a whole number (0-100 integers) that best reflects his/her pain as 0-30 for mild pain, 30-60 for moderate pain and 60-100 for sever pain

Secondary Outcome Measures
NameTimeMethod
Systolic Blood PressureOne hour before induction of general anesthesia, every 10 minutes till end of surgery, every 4 hours till end of the first 24 hours postoperatively, then every 8 hours till end of the next 24 hours

The pressure in the arteries during contraction of the heart

Peripheral oxygen saturationOne hour before induction of general anesthesia, every 10 minutes till end of surgery, every 4 hours till end of the first 24 hours postoperatively, then every 8 hours till end of the next 24 hours

An estimate of oxygenated hemoglobin concentration in blood. It is measured by pulse oximeter device

Time to first rescue analgesic requestUp to 48 postoperative hours

The time elapsed from termination of performing each block till the patient's request for analgesia. It resembles the duration of analgesia

Postoperative nausea and vomiting intensity scoreImmediately after recovery, every 4 hours till end of the first 24 hours postoperatively, then every 8 hours till end of the next 24 hours

Postoperative Nausea and Vomiting Intensity Scale: A scale that evaluates postoperative nausea and vomiting. It equals severity of nausea (1=mild, 2= moderate, 3= sever) x pattern of nausea (1=varying, 2= constant) x duration of nausea (in hours). At any time, if it is \< 50 or vomiting occurs once or twice, it is clinically unimportant (good outcome). If it is ≥50 or vomiting occurs 3 or more times, it is clinically important (bad outcome). The sum of all values will quantify the entire period of the study.

Heart rateOne hour before induction of general anesthesia, every 10 minutes till end of surgery, every 4 hours till end of the first 24 hours postoperatively, then every 8 hours till end of the next 24 hours

The number of heart beats per minute. A lower heart rate at rest implies a more efficient heart function, better cardiovascular fitness and less stress

Serum C-reactive protein (CRP)On hospital admission, 1 hour after induction of general anesthesia, 1st, 24th and 48th hours postoperatively

A protein synthetized by hepatocytes in response to systemic inflammation or tissue damage

Mean Blood PressureOne hour before induction of general anesthesia, every 10 minutes till end of surgery, every 4 hours till end of the first 24 hours postoperatively, then every 8 hours till end of the next 24 hours

: The average pressure in the arteries during one cardiac cycle. It is a better indicator for vital organs' perfusion than the systolic pressure

Total amount of rescue analgesic consumptionFrom the time of first analgesic request till the end of the first 24 hours, then till the end of the next 24 hours postoperatively

The total amount of morphine consumed by the patient for pain relief over the 48 hours postoperatively

CortisolAt 9 Am, 1 hour after induction of general anesthesia, 1st, 24th and 48th hours postoperatively

A steroid hormone secreted by adrenal cortex in response to stress and hypoglycemia
