Post Laparoscopy Shoulder Pain and Postoperative Trendelenburg Position

October 15, 2019 updated by: Joseph Nassif, American University of Beirut Medical Center

Effect of Postoperative Trendelenburg Position on Shoulder Pain After Gynecological Laparoscopic Procedures.

Laparoscopic surgery has become a standard of care for many gynecological surgeries due to its lower morbidity, pain and cost compared to open techniques. Unfortunately, the use of carbon dioxide (CO2) to insufflate the abdomen is a major contributor to post operative shoulder pain. Shoulder pain post laparoscopy is common and it is a major cause of patient dissatisfaction. The aim of our study is to evaluate the efficacy of positioning the patient in Trendelenburg, post operatively for 24 hours, on shoulder pain reduction. Our hypothesis is based on the assumption that complete CO2 deflation is not possible and that Trendelenburg positioning will help displace CO2 from the sub diaphragmatic area thus reducing the diaphragmatic and phrenic nerve irritation causing pain.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

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 prospective randomized controlled study with 54 patients in each of the two arms. Group S (control) will undergo the standard laparoscopic procedure and the patients will be placed in supine head up position postoperatively. In group T (interventional); the patients will be positioned in Trendelenburg position once fully awake and cooperative in the post-anesthesia case unit (PACU) and will remain in this position for the first 24 hours postoperatively. Postoperative NRS(numeric rating scale) score for shoulder pain and nausea will be collected at arrival to PACU, & 4, 6, 12 and 24 hours postoperatively. In addition, total amount of rescue pain and nausea medication used by the patient will be recorded. Data collected will be analyzed and compared between the two groups. The independent t- test will be used to compare postoperative shoulder pain, with NRS scores treated as continuous variable, between the two groups.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
No Intervention: Group S
Control group (Group S: 54 patients); this group will undergo the standard laparoscopic procedure (the procedure is done in Trendelenburg position). While in Trendelenburg position and prior to wound closure and with laparoscopic port valves open, the patient's abdomen will be passively deflated. The patients will be placed in supine head up position in the post anesthesia care unit (PACU).
Experimental: Group T
Intervention group (Group T: 54 patients); the patients will be subject to the same maneuver as in arm 1 prior to wound closure but will be positioned in a 20 degree Trendelenburg position once fully awake and cooperative in the PACU and will remain in this position for the first 24 hours post operatively, even after they are transferred to their rooms on the American University of Beirut Medical Center (AUBMC) floors. The maximum time allowed in a straight-up position will be three 15-minute intervals over a 24-hour period (the first interval being a clear fluids intake at 12 hours postoperatively).
Procedure: 20 degree Trendelenburg position
The patients in the intervention group will be placed in trendelenburg position postoperatively.
