Brief summary
The study will be conducted at the CALHN sites comprising The Queen Elizabeth Hospital and Royal Adelaide Hospital with patients who are scheduled for elective laparoscopic colonic surgery. The purpose of this study is to assess the efficacy of wound infiltration over the newer regional analgesic technique called erector spinae block (ESP) block for the postoperative analgesia.Efficiency is assessed by comparing pain scores, analgesics use and other outcomes measures analysed are, discharge time and clinical determinants of adverse effects. We hypothesize; that ultrasound-guided ESP block is superior to surgically guided wound infiltration in providing superior pain relief without major side effects.
Interventions
: Erector spinae plane (ESP) block Technique: It is single shot technique performed by anaesthetist ( one of the investigators) at the end of the surgical procedure in theatre. An in plane approach in the lateral position will be attempted under the ultrasound guidance. Using a 6- to 15-MHz high-frequency linear probe, Erector spinae (ES) muscles will be visualized at T8 transverse process 22g needle will be used to locate ES, after saline test dose 3mg/kg of ropivacaine (0.5%, 20 mL per side) w

This ESP block is monitored in recovery room and assessed how effective in providing post operative pain relief in colorectal surgery.
