IV Acetaminophen for Postoperative Pain Analgesia After Laparoscopic Hysterectomy

15 maggio 2018 aggiornato da: Noah Rindos, University of Pittsburgh

Intravenous Acetaminophen Versus Saline in Postoperative Analgesia After Laparoscopic Hysterectomy: A Randomized, Double Blind, Placebo Controlled Trial

The objective of this study is to quantify the change in post-operative pain scores and narcotic requirements in women receiving pre and post-operative IV acetaminophen compared to placebo in women undergoing laparoscopic hysterectomy.

Descrizione dettagliata

Gynecologic surgery has been revolutionized by the incorporation of minimally invasive techniques. Procedures that once resulted in multiple day hospital admissions are now being performed in outpatient surgery centers. Common factors that contribute to delayed discharge are inadequate postoperative pain control and increased nausea and vomiting. A multi-modal pain management approach is considered optimal at controlling postsurgical pain, which includes combining different analgesics that act in varying mechanisms. By using medications that act synergistically, the overall analgesia requirement can oftentimes be decreased.

Opioids have been found to be highly effective in controlling postoperative pain; however, are associated with dose-dependent risks including nausea, vomiting, constipation, urinary retention, sedation, and respiratory depression. Subsequently, non-opioid options are frequently desired in an attempt to minimize narcotic intake. In the United States, intravenous acetaminophen was approved by the US Food and Drug Administration (FDA) in November 2010 for the management of mild to moderate pain and the reduction of fever. Since this time, multiple studies have analyzed the role of intravenous acetaminophen in both acute and postoperative pain; however, none have been specific to laparoscopic hysterectomy. The primary study published evaluating intravenous acetaminophen in laparoscopic hysterectomies also included multiple other laparoscopic procedures from a variety of specialties including general surgery, urology, and urogynecology. In addition, the intravenous acetaminophen was started on average 19 hours after the conclusion of the case once the patient controlled analgesic was discontinued.

Improved postsurgical pain control achieved with intravenous acetaminophen may potentially lead to same day discharge after major laparoscopic gynecologic procedures. Same day discharge after laparoscopic hysterectomy has been shown to be a safe option with proper patient counseling and multi-modal pain medications. In addition, same day discharge is also associated with decreased health care expenditures. With continued efforts to cut hospital costs, the pressure to discharge patients earlier continues to be high.

The investigators propose that intravenous acetaminophen will improve post-operative pain control and decrease narcotic requirements for patients undergoing laparoscopic hysterectomies. Furthermore, The investigators expect to find decreased postsurgical nausea and vomiting and potentially quicker discharge to home. This could have a large impact on the field of gynecologic surgery as major procedures that once required overnight admission may now succeed at same day discharge.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Postoperative Pain
Lasso di tempo: 24 hours
The primary aim of this study is to compare overall post-surgical pain after hysterectomy as reported by the patients on a visual analog scale with a range of 0 to 10 where 0 is no pain at all and 10 is the worst pain that a person can imagine. Less pain is considered preferable to more pain. The theory is that patients who have intravenous acetaminophen will report less post-surgical pain.
24 hours

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Narcotic Medication Use
Lasso di tempo: 24 hours
The secondary outcome is comparison of narcotic pain medical requirements within the first 24 hours after surgery. The hypothesis is that the intravenous acetaminophen group will require less narcotic medications than the placebo group. Narcotic use in this study will be calculated by converting all narcotics (fentanyl, dilaudid etc) into standardized units of morphine using well validated conversion tables.
24 hours

Altre misure di risultato

Misura del risultato
Misura Descrizione
Lasso di tempo
Having a Feeling of General Well-being at One Month
Lasso di tempo: 4 weeks
Quality of recovery will be evaluated through the use of the validated Quality of Recovery-40 questionnaire. The hypothesis is that the intravenous acetaminophen group will experience an increased quality of recovery as compared to the placebo group.
4 weeks
Number of Participants Who Vomited Within 24 Hours of Operation
Lasso di tempo: 24 hours
A secondary aim of this study is to compare post-operative vomiting scores on post-operative day zero and one. Vomiting is reported as either having vomited or not vomited. The hypothesis is that the intravenous acetaminophen group will experience decreased vomiting compared with the placebo group.
24 hours
Readiness for Discharge
Lasso di tempo: 24 hours
Patient perception of satisfaction at time of discharge on post-operative day zero will be evaluated. The hypothesis is that intravenous acetaminophen group will experience increased satisfaction for discharge than the placebo group.
24 hours
Nausea Before Surgery as Compared to After Surgery
Lasso di tempo: 24 hours
A secondary aim of this study is to compare post-operative nausea on post-operative day zero and one as reported by the patients on a visual analog scale with a range of 0 to 10 where 0 is no nausea at all and 10 is the worst nausea that a person can imagine. Less nausea is considered preferable to more nausea. The hypothesis is that the intravenous acetaminophen group will experience decreased nausea compared with the placebo group.
