The benefits of routine oxytocics in the third stage of vaginal delivery are well established but it is unclear whether benefits are also obtained with cesarean delivery. In a previous survey, wide variation in the use of oxytocin at cesarean section was found among clinicians in the United Kingdom. The aim of the present survey was to assess possible differences in the use of oxytocin infusion in the management of blood loss at elective cesarean section among 5 countries in the United Kingdom (Republic of Ireland, England, Scotland, Wales, and Northern Ireland). Another aim was to look for and investigate any possible differences between clinician practice with regard to use of oxytocin and published guidelines on use of oxytocin regimens from these countries. The published guidelines were those of the National Institute for Health and Clinical Excellence (NICE), the Royal College of Obstetricians and Gynaecologists (RCOG) and Advanced Life Support in Obstetrics (ALSO). The survey response rate was 82.4% (391/474). A total of 346 responders (85%–95% for individual countries) reported use of a 5 IU oxytocin bolus. There was marked variability between some of the counties regarding routine use of an oxytocin infusion with 11% the lowest and 55% the highest. A slow bolus of 10 IU oxytocin was used by up to 14% of responders in some countries despite recommendations against this regimen in published guidelines. The choice among other oxytocin regimens in some countries also showed considerable variation from the country-specific published guidelines. For example, only 122 (40%) of the clinician practices in England and Wales use a 30 IU oxytocin infusion over 4 hours despite its recommended use by NICE, which covers both countries. These findings show a marked variation between practices in the 5 countries in the choice of an oxytocin regimen. Although there is general consensus for the use of the 5 IU bolus dose, considerable variation exists for both the use and dose of infusion. Clinical practices in specific countries deviate from published guidelines.
