Observational Study
Poor preoperative performance at Clock Drawing Test is associated with postoperative decline in olfaction in older patients: an observational pilot study.
Decline in olfaction may occur after general anesthesia, but the exact incidence and underlying physiopathology remain scarcely investigated. Olfactory dysfunction arises with aging and is known to be linked to cognitive impairment. In this pilot study, we evaluated the incidence of immediate postoperative decline in olfaction and its association with a preoperative cognitive test, performance at Clock Drawing Test (CDT), in a group of older patients. ⋯ Postoperative decline in olfaction occurred in 20.4% of older patients and was associated with poor preoperative performance at CDT.

Randomized Controlled Trial
Randomized comparison of effects of two different remifentanil dose on surgical conditions during endoscopic sinus surgery.
The combination of propofol and remifentanil results in better surgical field conditions during endoscopic sinus surgery than inhalation anesthesia. This study compared surgical field conditions between two groups receiving low or high concentration of remifentanil and hemodynamic variables using non-invasive cardiac monitoring. ⋯ When comparing the HR group and the LR group, the surgical condition was improved at 90 min after the start of surgery. MAP was lower in the HR group and this was a result of reduction in cardiac output primarily attributed to the decrease in heart rate rather than a decrease in stroke volume.

Randomized Controlled Trial
Effect of intraoperative muscle relaxation reversal on the success rate of motor evoked potential recording in patients undergoing spinal surgery: a randomized controlled trial.
Partial neuromuscular blockade (NMB) has been applied for some surgeries to reduce bleeding and prevent patient movement for spinal surgery. Sugammadex selectively binds to rocuronium in the plasma and consequently lowers the rocuronium concentration at the neuromuscular junction. In this study, we aimed to observe whether the success rate of transcranial motor-evoked potential (TceMEP) can be increased by sugammadex compared with partial NMB during spinal surgery. ⋯ Sugammadex can improve the success rate of motor-evoked potential monitoring compared with moderate neuromuscular blockade induced by continuous infusion of rocuronium in spinal surgery.

The opioid epidemic in the United States has had devastating consequences, with many opioid-related deaths and a significant economic toll. Opioids have a significant role in postoperative pain management. Here we aim to analyze differences in postoperative opioid and non-opioid pain medications regimens following common otolaryngological surgeries between two large tertiary care medical centers: the Milton S. Hershey Medical Center, USA (HMC) and The Chaim Sheba Medical center, Israel (SMC). ⋯ HMC demonstrated a significantly more permissive approach to both prescribing and consuming opioid medications for postoperative pain management than SMC for similar, common otolaryngological surgeries. Non-opioid alternatives and examining the cultural and medical practice-based differences contributing to the opioid epidemic should be discussed and reevaluated.

Hypnosis can be a beneficial complementary anesthesia technique for a variety of surgical procedures. Despite favorable scientific evidence, hypnosis is still rarely used in the operating room. Obstacles to implementation could be a lack of interest or training, misconceptions, as well as limited knowledge amongst anesthesiology teams. Hence, this study aimed to assess the interest, training, beliefs, and knowledge about hypnosis in the operating room staff. ⋯ Overall, anesthesia providers' attitude was in favor of using hypnosis in the operating room. Misconceptions such as a prolongation of the procedure, alteration of consent, lack of acceptability for patients, and limited indications were identified as potential barriers. These deserve to be challenged through proper dissemination of the recent scientific literature and exposure to practice.
