Observational StudyThe Relationship Between Women's Intention to Request a Labor Epidural Analgesia, Actually Delivering With Labor Epidural Analgesia, and Postpartum Depression at 6 Weeks: A Prospective Observational Study.
Intending to deliver with labour epidural analgesia and then receiving a labour epidural is associated with slightly lower rate of postnatal depression.

Multicenter StudyUtilizing Patient E-learning in an Intervention Study on Preoperative Smoking Cessation.
Patients who smoke put themselves at increased risk for serious surgical complications, yet it is not currently routine practice to educate patients about the risk of complications due to smoking. Computer-based smoking cessation programs are increasingly being utilized in the general population and may overcome some of the barriers such as lack of time, knowledge, and training to provide interventions. Our objective was to develop and implement a patient e-learning program designed for surgical patients as part of a multifaceted program aimed at assisting them to quit smoking and to determine the factors cross-sectionally and longitudinally associated with abstinence. ⋯ Our preoperative smoking cessation program resulted in a 7-day PP abstinence of 22% at 6 months. A multifaceted intervention including a patient e-learning program may be a valuable tool to overcome some of the barriers to help surgical patients quit smoking.

ReviewPhysiology and Role of Intraocular Pressure in Contemporary Anesthesia.
More than 26 million Americans suffer with cataracts, and with 3.6 million cataract extractions performed annually in the United States, it is the most common surgical procedure. The integrity of the delicate structures of the eye that mediate vision is dependent on the intraocular pressure (IOP). Yet, IOP acts to compress the vessels within the globe-akin to a Starling resistor-and is a key component that determines the ocular perfusion pressure, defined as the difference between arterial pressure and IOP. ⋯ Anesthetic management significantly influences the pressure changes in the eye throughout the perioperative period. Strategies to safeguard retinal perfusion, reduce the ischemic risk, and minimize the potential for expulsive bleeding must be central to the anesthetic techniques selected. This review outlines: important physiological principles; ophthalmic and general procedures most likely to develop damaging IOP levels and their causative factors; the effect of anesthetic agents and techniques on IOP; recent scientific evidence highlighting the significance of perfusion changes during surgery; and key aspects of postoperative visual loss and management approaches for high-risk patients presenting for surgery.
