UNASSIGNED
Most of the headache cases only require pain management in emergency department (ED). The present study aimed to evaluate the efficacy of intranasal lidocaine in this regard.
UNASSIGNED
In this clinical trial, adult patients with primary headache were randomly treated with 7.5 mg intravenous (IV) chlorpromazine and 1 ml intranasal lidocaine 2% (treatment) or normal saline 0.9% (placebo), and were compared 5, 15, and 30 minutes later regarding success rate using SPSS 21.
UNASSIGNED
100 patients were assigned to either treatment or placebo group. Number needed to treat of intranasal lidocaine at 5, 15, and 30 minutes were 4 (95% CI: 2.2 - 6.6), 3 (95% CI: 1.7 - 3.5), and 4 (95% CI: 2.3 - 15.9), respectively. These measures for absolute risk reduction were 30 (95% CI: 15.2 - 44.8), 44 (95% CI: 28.7 - 59.3), and 26 percent (95% CI: 6.3 - 44.3), respectively. Pain relapse occurred in 16% of treatment and 11% of control group within 1 hour of treatment (p = 0.402).
UNASSIGNED
It seems that, intranasal lidocaine along with IV chlorpromazine could result in more successful and faster management of primary headaches in ED.
