چکیده

conclusions intravenous acetaminophen administered before caesarean section reduced tachycardia after intubation, narcotic drugs administration during and after the operation and reduced pain in pacu. results patients in the saline group experienced more pain in the recovery room (vas 7.0 ± 1.24 vs. 6.15 ± 2.27; p value = 0.041) and required more fentanyl intraoperatively (150 µg vs. 87.7 ± 75; p value < 0.01) and meperidine postoperatively (12.88 ± 20.84 mg vs. 1.35 ± 5.73; p value = 0.002) than the paracetamol group. mean arterial pressure (map) changes were similar after intubation in the both groups (p value = 0.71), however, pulse rates showed greater changes following intubation in the saline group (p value = 0.01). objectives the aim of this study was to investigate the effect of intravenous acetaminophen (paracetamol) in blunting hemodynamic responses to endotracheal intubation and postoperative pain in parturient undergoing cesarean section by general anesthesia. patients and methods eighty parturients undergoing cesarean section by general anesthesia were randomly divided to receive either 15 mg/kg intravenous paracetamol (n = 40) or normal saline (n = 40) fifteen minutes before endotracheal intubation. mean arterial blood pressure (map) and pulse rates were compared at baseline and after intubation at one minute interval for five minutes between the two groups. the patients were also compared for postoperative pain intensity and analgesic requirement. background use of analgesics, especially opioids, before delivery during cesarean section for preventing hemodynamic changes after endotracheal intubation and postoperative analgesia is limited due to their adverse effects on the neonate.

Warming Endotracheal Tube in Blind Nasotracheal Intubation throughout Maxillofacial Surgeries.

INTRODUCTION Blind nasotracheal intubation is an intubation method without observation of glottis that is used when the orotracheal intubation is difficult or impossible. One of the methods to minimize trauma to the nasal cavity is to soften the endotracheal tube through warming. Our aim in this study was to evaluate endotracheal intubation using endotracheal tubes softened by hot water at 50 &...

Effect of preoperative administration of intravenous paracetamol during cesarean surgery on hemodynamic variables relative to intubation, postoperative pain and neonatal apgar.

Selection of anesthetic drugs for cesarean section requires many considerations. Anesthetic drugs for this purpose must prevent hemodynamic stress due to tracheal intubation, while inducing neonatal complications. This study was conducted to determine the effects of paracetamol given before induction of anesthesia on cardiovascular responses to tracheal intubation and postoperative pain in the ...
