Treatment of singultus following craniocerebral injury★Intranasal cavity drip infusion versus intramuscular injection of aminazine

BACKGROUND: Craniocerebral injury always accompanies with singultus, while frequent singultus may cause increased intracranial pressure. Simultaneously, respiratory alkalosis and cerebral hypoxia induced by respiratory disorder may aggravate craniocerebral injury.OBJECTIVE: To observe the therapeutic effects of intranasal cavity drip infusion of aminazine and intramuscular injection on singultus following craniocerebral injury.DESIGN: Contrast observation.SETTING: Department of Neurosurgery, Xi'an Aerospace General Hospital.PARTICIPANTS: A total of 102 patients with singultus following craniocerebral injury were selected from the Department of Neurosurgery, Xi'an Aerospace General Hospital from June 2001 to June 2006. Patients with craniocerebral injury were diagnosed with CT examination and randomly divided into nasal cavity medication group (n =62) and intramuscular injection group (n =40). There were 44 males and 18 females in the nasal cavity medication group and their mean age was (33±4) years; while, there were 26 males and 14 females in the intramuscular injection group and their mean age was (29±4) years. All patients and their relatives provided the confirmed consent. METHODS: Patients in the nasal cavity medication group were slowly dripped aminazine solution into bilateral nasal cavity with the dosage of 12.5 mg (0.5 mL). Patients who had no obvious effect or had mild improvement received the treatment once every 6 hours. The treatment was stopped if symptoms were also observed after the fifth medication. In addition, patients in the intramuscular injection group received intramuscular injection of 50 mg aminazine. Patients who had no obvious effect or had mild improvement received the treatment once every 6 hours. The treatment was changed if symptoms were also observed after the fifth medication.MAIN OUTCOME MEASURES: Therapeutic effects of different medications in the two groups.RESULTS: All 102 patients were involved in the final analysis. Effective rate in the nasal cavity medication group was higher than that in the intramuscular injection group, and there was significant difference (χ2= 11.882, P < 0.01). At 6 hours after onset of singultus, effective rate in the nasal cavity medication group was higher than that in the intramuscular injection group, and there was significant difference (χ2 =8.188, P < 0.01). CONCLUSION: Therapeutic effects of intranasal cavity drip infusion of aminazine on singultus following craniocerebral injury are superior to those of intramuscular injection.
