An unusual hurdle in a difficult airway of a short statured kyphoscoliotic pregnant patient for upper segment caesarean section
A middle aged thirty seven and half weeks pregnant dwarf with sever thoracic kyphoscoliosis presented for elective caesarean section in view of cephalopelvic disproportion. She had an anticipated anatomical difficult airway. Investigations revealed bilateral basal lung atelectasis, tricuspid regurgitation and mild pulmonary hypertension. low dose spinal anaesthesia with supplemental epidural anaesthesia allowed successful performance of surgery. Supplemental oxygen via face mask was provided but a steady rise in end tidal carbon dioxide appeared to indicate an impending airway disaster.
