Anaesthesia
-
We speculated that asymptomatic patients undergoing routine surgery might be at higher risk of subsequent cardiac events. We studied 183,534 patients with no prior admission for heart disease, aged 50-75 years, admitted electively for one of five operations considered medium to low risk of peri-operative cardiac morbidity, between January 1997 and December 2005. Controls were generated from linked records. ⋯ Of patients undergoing surgery, 20.2% died compared with 25.7% of controls (p < 0.001). Patients undergoing certain surgical procedures did not have a higher incidence of readmission for cardiac events, but had a general survival benefit compared with other elective hospital admissions. Assessment for surgery may represent a health benefit beyond the original surgery.

Case Reports
Spinal anaesthesia for caesarean delivery in a parturient with babesiosis and Lyme disease.
We present a case of a parturient with babesiosis and Lyme disease who was scheduled for elective caesarean section. The caesarean section was performed under spinal anaesthesia, and the patient had a coronary artery dissection 4 days postoperatively. Neuraxial anaesthesia and possible mechanisms for the coronary artery dissection in a patient with babesiosis and Lyme disease are discussed.
