subcutaneous emphysema is a rare complication of postoperative nausea and vomiting and can lead to airway compromise. we describe a case of delayed, severe subcutaneous emphysema after postoperative vomiting which fortunately did not lead to airway compromise and eliminated with conservative management. rough and difficult laryngoscopy and intubation, presence of clots and bloody discharge afte...

Background Intrathecal morphine (ITM) has proven to be excellent in reducing postoperative pain. However, its use is associated with the occurrence of nausea and vomiting (PONV). In this study, we wish compare efficacy between combination therapy granisetron dexamethasone versus alone on (PONV) parturients undergoing elective Caesarean delivery.Method This a prospective double-blinded, randomis...

In this double-blind, randomized, placebo-controlled study, we evaluated the efficacy and safety of different doses of prophylactic IV dexamethasone for postoperative nausea and vomiting (PONV) in 168 children (aged 2-15 yr) scheduled for strabismus surgery. Patients received IV dexamethasone 0.25 mg/kg (D 0.25), 0.5 mg/kg (D 0.5), 1.0 mg/kg (D 1), or saline (S) immediately after induction of g...

BACKGROUND To determine the incidence of Postoperative nausea and vomiting (PONV) in a high risk surgical group following studies in other predominately black populations that showed a lower rate of postoperative nausea and vomiting than that reported from Caucasian and Oriental populations. METHODS A retrospective observational survey was conducted in the University of Nigeria Teaching Hospi...

To the Editor: We, too, have noticed the phenomenon described by Perron et al.1 after a bolus injection of dexamethasone 8 mg iv. Our strategy to prevent this is to administer the dexamethasone immediately after the induction of general anesthesia. However, this might limit the efficacy of dexamethasone to prevent postoperative nausea and vomiting (PONV). The article by Wang compares the admini...

BACKGROUND Epidural opioids have excellent analgesic properties, but their side-effects limit their use in patient-controlled epidural analgesia. This study was designed to evaluate the effect of epidural naloxone on the side-effects of sufentanil, focusing on postoperative nausea and vomiting (PONV) in patients undergoing total knee replacement (TKR). METHODS After obtaining Institutional Re...

BACKGROUND Craniotomy patients have a high incidence of postoperative nausea and vomiting (PONV). This prospective, randomized, double-blind, multi-center study was performed to evaluate the efficacy of prophylactic ramosetron in preventing PONV compared with ondansetron after elective craniotomy in adult patients. METHODS A total of 160 American Society of Anesthesiologists physical status I...
