The Effects of Vasopressin and Oxytocin on the Fetoplacental Distal Stem Arteriolar Vascular Resistance of the Dual-Perfused, Single, Isolated, Human Placental Cotyledon

Anesthesia & Analgesia: September 2016 – Volume 123 – Issue 3 – p 698–702 AUTHORS: Downing, John W. MD et al BACKGROUND: Vasoactive agents administered to counter maternal hypotension at cesarean delivery may theoretically intensify the hypoxemic fetoplacental vasoconstrictor response and, hence, negatively impact transplacental oxygen delivery to the fetus. Yet, this aspect of their […]

Intrathecal Hydromorphone and Morphine for Postcesarean Delivery Analgesia: Determination of the ED90 Using a Sequential Allocation Biased-Coin Method

Anesthesia & Analgesia:September 2016 – Volume 123 – Issue 3 – p 690–697 AUTHORS: Sviggum, Hans P. MD et al BACKGROUND: Intrathecal (IT) morphine is considered the “gold standard” for analgesia after cesarean delivery under spinal anesthesia, most commonly administered at a dose of 100 to 200 μg. There is less experience with IT hydromorphone […]

Influence of Mechanical Ventilation on the Incidence of Pneumothorax During Infraclavicular Subclavian Vein Catheterization: A Prospective Randomized Noninferiority Trial

Anesthesia & Analgesia: September 2016 – Volume 123 – Issue 3 – p 636–640 AUTHORS: Kim, Eugene MD et al BACKGROUND: It remains unclear whether we have to interrupt mechanical ventilation during infraclavicular subclavian venous catheterization. In practice, the clinicians’ choice about lung deflation depends on their own discretion. The purpose of this study was […]

The Relationship Between Oxygen Reserve Index and Arterial Partial Pressure of Oxygen During Surgery

Anesthesia & Analgesia: September 2016 – Volume 123 – Issue 3 – p 626–633 AUTHORS: Applegate, Richard L. II MD et al BACKGROUND: The use of intraoperative pulse oximetry (SpO2) enhances hypoxia detection and is associated with fewer perioperative hypoxic events. However, SpO2 may be reported as 98% when arterial partial pressure of oxygen (PaO2) is […]

Lower Dose of Tranexamic Acid Favored for Arthroplasty Procedures

For the antifibrinolytic agent tranexamic acid, doses varying between 5 and 15 mg/kg failed to produce a dose-dependent drop in hemoglobin after total knee (TKA) or total hip arthroplasty (THA), leading study investigators to recommend using the lowest of these doses in orthopedic patients. “At my institution, we reviewed quite a bit of data while […]
