Brief summary

The aim of this trial is to evaluate the effect of high-dose glucocorticoid on inflammatory response and recovery after emergency laparotomy in participants with intestinal obstruction and perforated viscus. Primary outcome is the reduction of C-reactive protein on postoperative day 1. Secondary outcomes are organ specific complications in the post anaesthesia phase, endothel and inflammatory markers, fluid status, preload dependency, pain, lung function, nausea and mobilization during the first 5 days after surgery, . The investigators hypothesize, that a preoperative single high dose of glucocorticoid reduces systemic inflammatory response after emergency laparotomy.

Detailed description

Surgical trauma and accompanying inflammation results in increased capillary permeability leading to tissue edema. Since the vascular endothelium contributes to homeostasis, endothelial damage may increase the risk of cardiovascular and hemodynamic complications. Pre-operative high-dose glucocorticoids provide reduction in the inflammatory response after surgery, effective pain relief in several major surgical procedures, as well as reducing fatigue, impairing endothelial dysfunction, potentially amend fluid extravasation, edema and dyscoagulation and vasodilation. However, glucocorticoids have not been assessed in patients with peritonitis or intestinal obstruction, specifically, the impact on pain, fluid dynamics, respiratory as well as endothelial function and mobilization in both obstruction and perforation. In this study, patients will be randomized to either high dose dexamethason (1 mg /kg) or placebo (0,9% NaCl), administered as a single dose preoperatively. The investigatoris hypothesize that a preoperative single high dose of glucocorticoid reduces systemic inflammatory response after emergency laparotomy.

quick Sequential Organ Failure Assessment score, qSOFAAssessed once preoperatively and 4 times daily during the first 5 postoperative days

Peak flow measurementsOnce a day on postoperative day 1,3 and 5
Postoperative need for antiemetic and analgesic beyond standard courseOnce a day during the the first 5 postoperative days
Mobilization, The Cumulated Ambulation Score (CAS)Once a day on postoperative day 1,3 and 5The CAS describes the patient's independence with regard to three activities (getting in and out of bed, sit-to-stand-to-sit from a chair, and walking). Each activity is assessed on a three-point ordinal scale from 0-2 (0 = Not able to, despite human assistance and verbal cueing, 1 = Able to, with human assistance and/or verbal cueing from one or more persons, 2 = Able to safely, without human assistance or verbal cueing, use of a walking aid allowed) resulting in a total daily CAS score ranging from zero to six
Postoperative delirium via Confusion Assessment method scaleOnce a day during the the first 5 postoperative days1.a: Acute onset 1b: Fluctuating course, 2: inattention 3: disorganized thinking 4: altered level of conciosness At least one criterion must be met for a positive result
