Background: Post-dural puncture headache (PDPH) is commonly seen after neuraxial block and it usually lasts for up to two days or in some cases for up to two weeks. Several types of regimens have been suggested for treatment, such as theophylline and caffeine. This study aimed to evaluate the effects of aminophylline, paracetamol, and administration of aminophylline and paracetamol concurrently on prevention of PDPH.
Methods: In a double-blind randomized clinical trial, we evaluated 120 patients in four groups (n=30) undergoing spinal anesthesia for extremity surgery in educational hospitals of Isfahan University of Medical Sciences (Alzahra and Ayatollah Kashani Hospitals), Iran, from 2016 to 2017. In group A aminophylline was injected slowly intravenously (1.5 mg/kg), in group B paracetamol (1000 mg) was injected intravenously, in group C aminophylline and paracetamol was injected with the same dose and in control group (n=30) normal saline was injected intravenously. After patients entered the operating room, mean arterial blood pressure and heart rate were measured and oxygen saturation was monitored. Before spinal anesthesia, 15 minutes before leaving the recovery room, every 6 hours in first day and daily in first week after the surgery, incidence of PDPH in each group were evaluated. The frequency of nausea between the four groups was also studied.
Results: 42 patients (35%) out of the 120 ones suffered from headache. 40% of patients who had received aminophylline, 33.3% of patients who had received paracetamol, 20% of patients who had received aminophylline and paracetamol and 46.6% of patients who had not received any drug suffered from headache (P=0.05). The frequency of nausea was not significantly different between the four groups at any time. The average of heart rate, mean arterial pressure and oxygen saturation in recovery and 24 hours after operation were not significantly different between the four groups.
Conclusion: This study shows that intravenous administration of aminophylline and paracetamol significantly reduces the incidence of post-dural puncture headache (PDHP) in lower extremity surgery and we can use this regimen for prevention.
