Churg-Strauss syndrome or eosinophilic granulomatosis with polyangiitits (EGPA) is a rare multisystem disorder. A case of anaphylactic shock after induction of anesthesia, as the initial clinical presentation of Churg-Strauss syndrome in a 15-year-old girl is reported. It is extremely rare to see pediatric patients with previous perioperative anaphylaxis receiving future anesthesia; a multidisciplinary approach including allergist, rheumatologist, anesthesiologist, and surgeon is necessary in order to provide a better future anesthetic plan.
Introduction: Ondansetron, a selective 5-hydroxytryptamine 3 (5-HT3) receptor antagonist, commonly used as an antiemetic has been proven in recent studies to be effective for the prevention of spinalinduced hypotension for elective cesarean section.
Methods:One hundred and thirty-eight healthy primigravida parturients scheduled for elective cesarean section were randomly assigned to three groups. Participants in the ONDA4, ONDA8, and CONTROL groups received 4 mg of ondansetron, 8 mg of ondansetron and normal saline respectively, 10 minutes before spinal anesthesia. Spinal anesthesia was performed at L3-L4 interspinous space, with 1.7 ml ropivacaine 0.75% and 15 mcg of fentanyl, via a 27 G pencil point needle. Blood pressure and heart rate were recorded upon arrival at the operating room, after preloading with 500 ml of 6% hydroxyethylstarch, at the time of spinal injection, and at oneminute intervals for 10 minutes thereafter. Blood pressure and heart rate values, total phenylephrine (mcg) or/and ephedrine (mg) doses, the incidence of maternal nausea/vomiting/shivering, umbilical artery pH and Apgar scores at 1 and 5 min were recorded. Time for the sensory block to reach T4 and regress to T7 dermatome, and the time for the motor block to reach Bromage scale 3 and to regress to Bromage scale 1, were also noted.Results: There were no differences between groups in hemodynamic parameters or doses of vasoactive agents used, sensory or motor block characteristics, incidence of nausea/vomiting, umbilical artery pH or Apgar scores of the neonates.
Conclusion:Our results failed to demonstrate the significance of ondansetron in preventing maternal hypotension following spinal anesthesia for cesarian section.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
