Modified Enhanced Recovery Program in Emergency Surgery (MERES) (MERES)

November 26, 2018 updated by: Pirogov Russian National Research Medical University

Evaluation of Modified Enhanced Recovery Program in Emergency Surgery

Laparoscopic appendectomy (LA) is a widespread surgical procedure. Patients may develop considerable postoperative pain and dyspepsia resulting in prolong in-hospital stay. Almost 10% of patients develop postoperative complications. Enhanced recovery after surgery (ERAS) program has proven its effectiveness in elective surgery and can theoretically improve outcomes of LA. To date there is no ERAS program for LA. The aim of the study was to investigate the safety and efficacy of a modified ERAS protocol in LA.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A modified ERAS (mERAS) protocol was investigated. The study is a prospective, randomized nonblinded. All patients underwent LA. Modified ERAS protocol included patient informing, limitation of drainage use; intraperitoneal anesthesia with long-acting anesthetics; low-pressure pneumoperitoneum; early mobilization and oral nutrition. Pain level was assessed in rest using visual analogue scale (VAS). The primary endpoint was postoperative length of stay (pLOS).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
