Douglas B. Craig, W.M. Wahba, Hillary Don ⋯ The work of Drs. D. Craig et al. published in the Journal more than 40 years ago was seminal to our understanding of how patient positioning has an important influence on lung volumes and on the age-related relationship between FRC and CV.

Comment
From the Journal archives: Be alert to the risk of unexpected prolonged postoperative hypoxemia!
In 1978, Drs. R Knill and A. Gelb published the results of a study to measure the effect of subanesthetic levels of halothane on the ability of fit volunteers to respond to sustained hypoxia, and to determine how long potentially hazardous levels of halothane persist after a brief non-complex surgical procedure in healthy patients. The purpose of this commentary is to highlight the historical context of their findings and the impact of their work on our modern day practice of anesthesia. ⋯ Subanaesthetic halothane: Its effect on regulation of ventilation and relevance to the recovery room. Can Anaesth Soc J 1978; 25: 488-94.

Review Meta Analysis Comparative Study
Comparison of propofol and volatile agents for maintenance of anesthesia during elective craniotomy procedures: systematic review and meta-analysis.
Both propofol and volatile anesthetics are commonly used for maintenance of anesthesia in patients undergoing neurosurgical procedures. The effects of these two classes of drugs on cerebral hemodynamics have been compared in many clinical trials The objectives of this review were to evaluate the cerebral hemodynamic effects, operative conditions, recovery profiles, postoperative complications, and neurological outcomes of propofol-based vs volatile-based anesthesia for craniotomy. ⋯ Propofol-maintained and volatile-maintained anesthesia were associated with similar brain relaxation scores, although mean ICP values were lower and CPP values higher with propofol-maintained anesthesia. There are inadequate data to compare clinically significant outcomes such as neurological morbidity or mortality.

Aortic dissection is an infrequent but serious condition that often requires immediate operative intervention. We explore recent developments in the classification of aortic dissection and perioperative transesophageal echocardiography that assist with quantifying the severity of disease and facilitate its management. ⋯ Developments in the classification of aortic dissection have improved our perspective and understanding of the key presenting features that affect mortality. Improvements in patient outcome may be achieved in part by appropriately timed echocardiography-guided surgery.
