About this study

Official title: A Randomized, Double Blind, Study to Evaluate the Efficacy of Nasal Nicotine Spray to Reduce Post-Operative Opioid Requirements in Nonsmokers in Elective Laparoscopic Bariatric Surgical Patients

This prospective, randomized, double-blind study will enroll nonsmoking female subjects undergoing laparoscopic bariatric surgery under general anesthesia. The hypothesis of this study is that female nonsmokers who receive nicotine via nasal spray immediately before waking up from anesthesia will need less pain medications 24 hours after the surgery compared to the subjects who receive placebo spray.

Read the detailed description

Though nicotine is known to be a mild analgesic, its use in the peri-operative period to reduce postoperative opioid requirements has only recently been investigated. In nonsmokers it has been shown to reduce postoperative pain and opioid requirements in both female patients undergoing uterine surgery and male patients undergoing prostatectomy. We have recently confirmed these findings in women undergoing uterine surgery by open, laparoscopic and vaginal approaches. In this study we found a 30% mean reduction of 24 hour postoperative opioid requirements following the administration of a 3 mg dose of nicotine nasal spray. Two previous studies with perioperative transdermal nicotine found that increasing doses of nicotine and increasing serum levels of nicotine were associated with higher rates of nausea. In our study, we found that the administration of nasal nicotine was associated with a transient increase of postoperative nausea and vomiting (PONV), but this was limited to the recovery room (PACU) stay. Two studies of nasal nicotine where antiemetics were prophylactically administered did not report the incidence of nausea. In our study, antiemetics were used as rescue medications only. Thus, it is unclear if the prophylactic administration of anti-emetics would effectively counteract the transient emetogenic effect of a small dose of nasal nicotine.

Laparoscopic bariatric surgery is becoming an increasingly popular treatment of morbid obesity. We recently performed a detailed analysis of postoperative pain and opioid requirements among patients that had this type of surgery and found that among non-smokers severe pain (pain > 7/10 on a 10 point scale) was commonly experienced (35%) despite substantial amount of postoperative opioid use (mean 68 mg oral morphine equivalents) and non-opioid analgesics in the first 24 hours. Because obesity related sleep disorders exceed 70% of patients undergoing bariatric surgery, and those disorders are exacerbated by opioids, potential therapies that could reduce postoperative opioid requirements in these patients have substantial value. Further, delayed nausea often poses a problem for these patients meeting hospital discharge criteria, and opioids used for analgesia aggravates this problem. Thus, the use of nasal nicotine could reduce the amount of opioid these patients require for postoperative analgesia. Combined with aggressive antiemetic prophylaxis against PONV, nasal nicotine could paradoxically and indirectly reduce the incidence of nausea in these patients by decreasing postoperative opioid requirements. The proposed study is a randomized clinical trial examining how nicotine affects recovery of female non-smokers undergoing bariatric surgery from general anesthesia. We will test the hypothesis that nicotine, administered in a nasal spray immediately before emergence from anesthesia, will reduce postoperative opioid requirement and postoperative pain. A secondary outcome is to assess if the routine administration of prophylactic antiemetic therapy prevents increased PONV associated with nicotine administration.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Postoperative Opioid Use During the Postanesthesia Care Unit (PACU) Stay, and the First 24 Hours Postoperatively

    Opioid use was calculated in intravenous morphine equivalents (iv MEQ) according to the Mayo Clinic Pharmacy opioid conversion calculator based on the recommendations from the American Pain Society. Specifically, the following conversion was used: 10 mg in MEQ=100mcg iv fentanyl=1.5 mg iv hydromorphone=20mg oral oxycodone=30mg oral hydrocodone.

    Measured: During PACU stay (approximately 94 minutes after operation), 24 hours after operation

Secondary outcomes (2)
  1. Number of Participants Who Needed to Use Antiemetic Medication in the PACU

    Rescue antiemetic therapy was 0.625 mg droperidol. Recalcitrant postoperative pain, nausea and vomiting (PONV) was treated per discretion of the supervising anesthesiologist.

    Measured: 24 hours postoperatively.

  2. Numeric Pain Score

    Upon arrival in the PACU and at least every 30 minutes thereafter while in the PACU, the subject was asked to report pain using a numerical pain score for current pain at rest from 0 (representing no pain) to 10 (representing the worst imaginable pain).

    Measured: on admission, 30 minutes, 60 minutes, at discharge

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Nasal Nicotine Spray and Nasal Normal Saline Spray in people with Pain, Postoperative, run by Toby Weingarten at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Jun 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Postoperative Opioid Use During the Postanesthesia Care Unit (PACU) Stay, and the First 24 Hours Postoperatively (time frame: During PACU stay (approximately 94 minutes after operation), 24 hours after operation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01194089, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
