ReviewAnalgesia nociception index and high frequency variability index: promising indicators of relative parasympathetic tone.
At present, there is no objective and absolute measure of nociception, although various monitoring techniques have been developed. One such technique is the Analgesia Nociception Index (ANI), which is calculated from heart rate variability that reflects the relative parasympathetic tone. ANI is expressed on a non-unit scale of 0-100 (100 indicates maximal relative parasympathetic tone). ⋯ Unlike ANI, HFVI can be displayed along with other biometric information on the Root® monitor. ANI/HFVI monitoring may affect the prognosis of not only patients in the perioperative period but those in ICU, those who receive home medical care, or outpatients. In this article, we present an updated review on ANI that has been published in the last decade, introduce HFVI, and discuss the outlooks of ANI/HFVI.

Observational StudyEvaluation of fibrinogen concentration by clot firmness using a dielectric blood coagulation test system.
To determine if fibrinogen concentration can be evaluated by dielectric permittivity changes in dielectric blood coagulation testing (DBCM) during cardiovascular surgery with cardiopulmonary bypass (CPB). ⋯ DCS variables showed a significantly strong correlation with plasma fibrinogen concentration, and the diagnostic performance for hypofibrinogenemia was comparable to that for FIBTEM MCF. This novel methodology has the potential to provide a point-of-care test with sufficient accuracy for the detection of perioperative hypofibrinogenemia during cardiovascular surgery with CPB.

Randomized Controlled TrialDeep breathing alleviates propofol-induced pain: a prospective, randomized, single-blind study.
Propofol is commonly used to induce general anesthesia; however, the pain caused during propofol injection is a disadvantage. This study aimed to assess whether deep breathing attenuates propofol injection pain. ⋯ Deep breathing could be an easy, safe, and inexpensive method for reducing pain during propofol injection.

Randomized Controlled TrialSingle-dose intravenous nefopam on postoperative catheter-related bladder discomfort in patients undergoing transurethral resection of prostate: a randomized, double-blind placebo-controlled trial.
Transurethral resection of prostate (TURP) with postoperative catheter traction can lead to significant catheter-related bladder discomfort (CRBD). This condition causes many postoperative complications and low patient satisfaction. This study aimed to evaluate the effectiveness of preoperative single-dose intravenous nefopam on the incidence and severity of CRBD and its adverse effects. ⋯ Single-dose nefopam significantly reduced the incidence and severity of CRBD in patients undergoing TURP with urinary catheter traction at 6 h after the procedure and before the end of catheter traction without increasing the adverse effects.

Effect of fibrinogen replacement therapy on bleeding outcomes and 1-year mortality in patients undergoing thoracic aortic surgery: a retrospective cohort study.
This study aimed to examine the effect of fibrinogen replacement therapy with cryoprecipitate or fibrinogen concentrate on bleeding outcomes and 1-year mortality in patients undergoing thoracic aortic surgery. ⋯ The results of this study indicate that 2-3 g of fibrinogen replacement reduces the incidence of major bleeding in patients with hypofibrinogenemia during cardiopulmonary bypass in thoracic aortic surgery.
