Abstract

Introduction:

Although there are multiple analgesia techniques, opioids remain the most widely used drug for pain control. Postoperative Nausea and Vomiting (PONV), sleepiness, respiratory, and gastrointestinal disorder are common complications of postoperative opioid use, which makes the decrease in opioid demand, through combination with non-opioid agents, desirable. Dexmedetomidine (DEX) is an alpha2-adrenergic agonist with sedative and anxiolytic effects. Recently, some studies proved the evidence of its notable opioid-sparing effect. Furthermore DEX, compared to opioids, seems to have the advantage of not inhibiting spontaneous breathing.

Aim:

This systematic review protocol aims to define the analgesic effect of perioperative DEX infusion and the cumulative opioid consumption of patients undergoing general anesthesia.

Methods:

The review will be conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta- Analysis Protocols (PRISMA- P) statement and the Cochrane recommendations for Systematic Reviews of Interventions.

Results:

The primary outcomes will be 1) The effect of DEX infusion, on pain control, compared to placebo or other treatments and 2) The opioid-sparing effect of DEX infusion compared to placebo or other treatments. The secondary outcome will be a) Respiratory depression, b) Hypotension requiring fluid infusion and/or amine, c) Bradycardia requiring vasoactive drugs, d) Needing of prolonged hospital stay, e) PONV and gastrointestinal disorders.

Conclusion:

A sub-analysis is planned for i) The type of surgery performed, ii) Patient’s gender, iii) Patients age. If possible, a meta- analysis (including sub-analysis and sensitivity analysis for all assessed outcomes) will be performed. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach will be followed to create a Summary of Findings.

The Registration Number for this Systematic Review is CRD42018086687.

Keywords: Dexmedetomidine (DEX), Opioid consumption, Perioperative pain, Postoperative Nausea and Vomiting (PONV), Analgesic effect, Bradycardia.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."
