The purpose of this report is to describe a new complication of epidural blood patch for inadvertent dural puncture. A dural tap in an obstetric patient was managed initially with a prophylactic blood patch via the epidural catheter. Despite this, 48 hr later, she developed post-dural puncture headache, neck, and shoulder pain, and was given a second epidural blood patch. ⋯ There were no further sequelae. Although severe complications of epidural blood patch are rare, they are alarming. Exacerbation of the original symptoms of post-dural puncture headache caused by, or following, epidural blood patching has not previously been reported.

The use of epidural analgesia has become so widespread in recent years that many women are now requesting repeat epidural analgesia for their second or subsequent labour. This study examines the incidence of problems at insertion and of inadequate block in 71 multiparae having second epidurals compared with 150 primiparae having their first epidural. ⋯ Epidurals were inserted at a greater dilatation (P < 0.05) and there was a shorter time to delivery (P < 0.01) in the multiparous group. We conclude that unilateral block is thus more common in women receiving repeat epidurals.

Randomized Controlled Trial Clinical Trial
Sugarless gum chewing before surgery does not increase gastric fluid volume or acidity.
Patients occasionally arrive in the operating suite chewing gum despite instructions to avoid oral intake for a specific number of hours before surgery. Some anaesthetists are hesitant to proceed with these patients fearing an increase in gastric volume and acidity. This study was undertaken to determine if gum chewing increased gastric volume and acidity. ⋯ There was no difference between groups in terms of gastric volume or pH. In addition, there was no relationship between gastric content and the length of time from gum discard to induction or the length of time gum was chewed. In conclusion, the data suggest that induction of anaesthesia is safe and surgery does not need to be delayed if a patient arrives in the OR chewing sugarless gum.

Case Reports
Complications of continuous epidural infusions for postoperative analgesia in children.
To determine the incidences of side effects and complications associated with the use of epidural analgesia for infants and children at the Alberta Children's Hospital, we reviewed our experience over a two-year period. A database was established for recording management, side effects and complications of each epidural, and this is a retrospective review of that database. Problems were identified as complications if there was a need for medical intervention related to the patient complaint, and if the intervention was documented in the patient record. ⋯ Early discontinuation of the epidural occurred in 41 cases, technical problems with the epidural catheter being the commonest reason (21 cases). Although three potentially serious complications were identified (one catheter site infection, one seizure, one respiratory depression) none was associated with lasting consequences. The majority of complications associated with the use of epidurals were minor and easily remedied.(ABSTRACT TRUNCATED AT 250 WORDS)
