Intranasal Lidocaine for Prevention of Postoperative Nausea and Vomiting.

Phase 4
Withdrawn
Conditions
Postoperative Nausea and Vomiting
Interventions
Drug: 2% Lidocaine HCl topical solution
Registration Number
NCT04810494
Lead Sponsor
Milton S. Hershey Medical Center
Brief Summary

Postoperative nausea and vomiting (PONV) are common and continue to be persistent problems following general anesthesia. Intranasal lidocaine has been used for the treatment of migraine. The theoretical basis for this effect of intranasal lidocaine on migraine relief is reported to be due to its action on the sodium receptors within the sphenopalatine ganglion. Although there is no reported association between PONV and migraines, injecting lidocaine within the sphenopalatine ganglion has proven to be effective in reducing PONV in endoscopic sinus surgery. The purpose of this study is to investigate the efficacy of intranasal 2% lidocaine in preventing PONV.

Detailed Description

Postoperative nausea and vomiting (PONV) is a common complication following general anesthesia.\[1\] In the absence of prophylaxis, it can occur in greater than one third of the patients undergoing surgery, and the incidence is even higher in patients with predisposing risk factors.\[2\] Surgical procedures that have been shown to be associated with a high incidence of PONV include breast, gynecologic, abdominal, and thyroid surgeries.\[3-5\] Although PONV usually resolves with treatment, its occurrence can increase postoperative morbidity, increase hospital cost, and prolong hospital length of stay.\[1-6\]Despite numerous available prophylactic treatments and proposed strategies, the incidence of PONV continue to be high given its complex pathogenesis.\[1\]

Lidocaine is a local anesthetic and its intravenous administration has been used as an adjuvant for the treatment of postoperative pain.\[7\] Intranasal lidocaine has also been used for the treatment of pain, specifically migraine, with significant relief of nausea.\[8\] The theoretical basis for this effect of intranasal lidocaine on migraine relief is reported to be due to its action on the sodium receptors within the sphenopalatine ganglion.\[9\] Although there is no reported association between PONV and migraines, injecting lidocaine within the sphenopalatine ganglion has proven to be effective in reducing PONV in patients undergoing endoscopic sinus surgery.\[10\]

Due to the complex mechanism of PONV, proven benefits of lidocaine on pain and possibly nausea, and previously shown benefit of sphenopalatine block in reducing PONV, we hypothesize that intranasal lidocaine could provide effective prophylaxis for PONV.

Primary Outcome Measures
NameTimeMethod
Incidenceup to 1 day

The incidence of nausea and/or vomiting will be measured by asking the nurse and patient.

Secondary Outcome Measures
NameTimeMethod
Duration of stay in PACU.up to 1 day

Duration (in hours) in PACU phase 1 will be recorded, this is typically up to 4 hours.

Severityup to 1 day

Severity of PONV will be measured in PACU phase 1. The severity of PONV will be measured as per the scale described by Eberhart et al.\[12\] \[None (absence of nausea and vomiting), mild (the patient suffered only mild nausea), moderate (the patient suffered 1-2 emetic episodes or moderate or severe nausea without exogenous stimulus and anti-emetics were required), and severe (the patient vomited at least once or experienced nausea at least twice, and anti-emetics were required at least once).

Duration of nausea and/or vomitingup to 1 day

Duration of nausea and/or vomiting as measured by patient report and physician/nursing observation. This will take place during PACU phase 1.

IntensityAt 6 hours after surgery or discharge home, whichever occurs first

Intensity will be measured with the validated PONV intensity scale created by Wengritzky et al.\[11\] This scale ranges from a value of 0 to 50. Clinically important PONV is defined as total score of 50.

Patient satisfactionAt 6 hours after surgery or discharge home, whichever occurs first

The patients will be asked to grade their satisfaction level as very satisfied, satisfied, dissatisfied, or very dissatisfied)

Rescue treatmentsup to 1 day

Use of pharmacological antiemetics or other rescue treatments for postoperative nausea (PON) or PONV in the PACU (Phase 1). This will include the name of the medications administered, frequency, and doses.
