Intrathecal anaesthesia in patients under 45 years: incidence of postdural puncture symptoms after spinal anaesthesia with 27G needles.

Postoperative headache and backpain has limited the use of intrathecal anaesthesia in younger patients (15-45 years). We studied postoperative complaints among 133 healthy young patients (mean age 30.0 years, 47% females) who received spinal anaesthesia with a 27G needle. Postoperatively, 5 patients (4%) complained of postdural puncture headache (PDPH), 18 (14%) reported nonspecific headache, while 27 (20%) suffered from backpain. PDPH was not related to sex, age, day-care surgery, number of puncture attempts, or obstetric procedures. Backpain was significantly more common among females, and among in-patients. One hundred and sixteen patients (87%) would accept spinal anaesthesia if they were to undergo the same surgical procedure again. Compared to other studies, we find the incidence of postanaesthetic complaints to be acceptable, also among day-care patients. The PDPH seemed to be lightly incapacitating, and only one patient required blood patching.
