Piglets are popular for studies of respiratory and cardiovascular function, but opioid analgesics are contraindicated in these studies because of central nervous system depression. We evaluated two nonopioid analgesics for postoperative pain relief following implantation of a central arterial catheter via an inguinal incision. Animals were randomly assigned(More)
Ventilatory responses (VRs) were measured via a sealed face mask and pneumotachograph in 30 unsedated, mixed-breed miniature piglets at 12.6 +/- 2.3 days of age (day 1) and then repeated after seven daily 24-min exposures to 10% O(2)-6% CO(2) [hypercapnic hypoxia (HH)]. Arterial blood was sampled at baseline, after 10 min of exposure, and after 10 min of(More)
Exposure to cigarette smoke is a risk factor for the sudden infant death syndrome (SIDS), but the ability to distinguish between the neuropathological effects of pre- versus postnatal exposure is limited in the clinical setting. To test whether postnatal nicotine exposure could contribute to the increased neuronal expression of apoptotic markers that we(More)
