Research describing opioid misuse in children after surgery currently describes single specialties, short follow-up, and heterogeneous data not conducive to comparative discussion. Our primary objective was to quantify opioids prescribed to pediatric surgical patients on discharge from hospital. Secondary objectives were quantifying opioids remaining unused at four-week follow-up, and family attitudes to safe storage and disposal. ⋯ These findings confirm overprescribing of opioids to pediatric surgical patients. Families tend not to return opioids that exceed post-discharge analgesic requirements at home and many of the reported disposal methods are unsafe. We recommend future studies focus on optimizing opioid prescriptions to meet, but not excessively surpass, home pain management requirements, and to encourage safe opioid disposal/return methods.

The purpose of this study was to investigate myometrial contractility induced by oxytocin in women with advanced maternal age (AMA) and morbid obesity (MO). We hypothesized that both oxytocin-pretreated and oxytocin-naïve myometrial tissues from women of AMA and women who are MO would exhibit poor myometrial contractility compared with women that are younger and of normal body mass index (BMI). ⋯ Oxytocin pre-treatment reduced myometrial contractility in AMA and control group women compared with their oxytocin-naïve counterparts, as a function of the desensitization phenomenon. Attenuated oxytocin-induced myometrial contractility in MO women in both oxytocin-pretreated and oxytocin-naïve samples suggests that these women have intrinsically reduced uterine contractile ability.
