Goal Oriented Anaesthetic Management for Caesarean Section in a Parturient With Pituitary Tumour

Abstract

BACKGROUND AND OBJECTIVE: Anesthesia for Pregnancy with pituitary tumours is a challenge to an Anesthesiologist, requires careful preoperative assessment and meticulous perioperative management to achieve optimal safety of mother and fetus. There are very limited studies in literature to guide the anaesthetic management of such patients. Here we report the successful Anaesthetic management of a parturient with pituitary tumour with epilepsy posted for emergency caesarean section. PRESENTATION, DIAGNOSIS, MANAGEMENT: A 25 year young woman, G2P1L1, a known epileptic, diagnosed with pituitary macroadenoma presented at 40 weeks of gestation with severe Oligohydramnios (AFI-4cm) was posted for an emergency caesarean section. Following consultation with the obstetrician, neonatologist and the neurosurgeon the decision was made to proceed with caesarean section under general anesthesia. Rapid sequence induction and intubation was performed with inj Thiopentone sodium and inj Rocuronium and was maintained with Isoflurane, titrated to maintain the stability of mean arterial pressure until extraction. A live 4. 25kgs male child was born with Apgar scores of 8 and 9 at 1 and 5 mins respectively. Following extraction 10U run as infusion in Ringers lactate. Intraoperative analgesia was administered after extraction. Dexmedetomedine infusion was used. Postoperative period was uneventful. DISCUSSION & CONCLUSION: Management of obstetric patients with pituitary tumour is complex, requiring knowledge of the physiological effects of pregnancy on tumour size and labour on intracranial pressure. General anesthesia combined with multimodal balanced analgesia is associated with a favorable outcome. General anaesthesia using Thiopentone, Fentanyl, Dexmedetomedine and titrated dose of Isoflurane was used in our case were found to be safe with adequate hemodynamic stability and postoperative pain control. A team approach involving the Anaesthethesiologist, obstetrician, neonatologist and neurosurgeon is recommended for appropriate management of such parturient.
