Clinical Trial Summary

Continuous thoracic epidural analgesia plays a very vital role in patients undergoing exploratory laparotomy. It not only supports a stable perioperative hemodynamics but also helps in early return of bowel activity.

Description:

Intestinal perforation is one of the commonest surgical emergency that the investigators encounter in emergency. Perioperative management of most of such patients is a challenging task for the anesthesiologist, as patients are often hemodynamically unstable at the time of their presentation to emergency. Usual plan of anesthesia for these patients is general anesthesia with or without an epidural block. In routine practice the investigators often place an epidural catheter, primarily for postoperative analgesia, unless there is some contraindication to epidural analgesia. Most often lower thoracic epidural is preferred because of longer length of the laparotomy incision. Thoracic epidural analgesia with local anesthetic (LA) is not only effective in managing the post-operative pain; it is also helpful in supplementing intra-operative analgesia with reduced requirement of anesthetic, muscle relaxant and the analgesic (opioid) drugs. In addition, it has also been reported to be associated with early return of gut motility.

It appears that absent / significantly reduced pain leads to lesser stress response, leading to less sympathetic activation and lesser catecholamine release. As catecholamines are inhibitory to gastrointestinal motility, earlier return of gastro intestinal (GI) motility can be achieved by reducing perioperative pain by continuous epidural analgesia. Moreover, an effective epidural analgesia with LA results in avoidance of opioid analgesics for optimal perioperative pain relief, which too may be helpful in achieving earlier return of gut motility.

Thus the investigators aimed at determining the effect of continuous thoracic epidural analgesia on return of gut motility in patients undergoing emergency exploratory laparotomy following intestinal perforation and compare it with those in whom epidural analgesia was not used.

• Analgesia, Epidural
• Emergencies

Intervention

Procedure:
• Epidural catheter placement
After explaining about the procedure an 18 Gauge epidural catheter was inserted into thoracic 11-12 inter vertebral space under strict asepsis. Before inserting the epidural needle same space was infiltrated with adequate amount of 2% Lignocaine with Adrenaline (1: 200,000) to make the procedure pain free. Epidural space was confirmed by loss of resistance technique.
