The management of cardiac arrest in pregnancy is an important task for the emergency physicians. Some reasons for cardiac arrest are reversible and should be recognized and managed promptly. Cardiopulmonary resuscitation follows general advanced cardiac life support guidelines with several modifications for pregnant women, taking into account the lives of both mother and fetus. Here, we present the case of 23-year-old pregnant patient who came to Guru Nanak Dev Hospital, Amritsar; in shock, had a cardiac arrest, successfully resuscitated in Intensive Care Unit (ICU), delivered by emergency cesarean section and was discharged from ICU on 9(th) day in healthy state.

Clonidine added to bupivacaine prolongs the duration of anesthesia and postoperative analgesia with minimal side effects. Ropivacaine has lower lipid solubility and better safety profile as compared to bupivacaine. This study is designed to evaluate the effects of low-dose clonidine when added to hyperbaric ropivacaine. ⋯ Addition of low-dose clonidine to intrathecal hyperbaric ropivacaine causes a significant prolongation of the duration of sensory and motor blockade as well as postoperative analgesia compared with saline placebo. However, it increases the incidence of hypotension and bradycardia which can be managed with routine clinical measures.

Dexmedetomidine and clonidine are commonly used drugs for sedation during regional anesthesia. However, data regarding arousal time from sedation with these drugs is sparse. Hence, we designed a study to compare arousal time from sedation with dexmedetomidine and clonidine during spinal anesthesia. We also tried to find out the correlation between clinical and objective method used for assessing the depth of sedation. ⋯ Intravenous dexmedetomidine infusion has shorter arousal time from sedation than clonidine during spinal anesthesia. A strong correlation exists between BIS and RSS during recovery from sedation.

Nausea and vomiting causes distress to patients and increases surgical complications. Though various antiemetics are available, their effectiveness and fetal safety profile when used in parturient remains debatable. This randomized, double-blind, comparative study was designed with an aim to compare the antiemetic effects of ondansetron and glycopyrrolate during cesarean section. ⋯ Effect of glycopyrrolate on nausea and vomiting during cesarean section are comparable to ondansetron, but with an increased incidence of dry mouth. Glycopyrrolate has no effect on hypotension or additional analgesic requirements, but the incidence of bradycardia is significantly less.

A sustained and effective oropharyngeal sealing with supraglottic airway (SGA) is required to maintain the ventilation during laparoscopic gynecological surgery in the Trendelenburg position. This study was conducted with I-gel™ and ProSeal LMA™, two prototype SGA devices with a gastric access. ⋯ Both I-gel and PLMA are effective for ventilation in gynecological laparoscopic surgeries. However, PLMA provides better sealing as compared to I-gel.
