Randomized Controlled Trial0.125% 8 ml/h v.s. 0.25% 8 ml/h of levobupivacaine in continuous paravertebral block for postoperative analgesia in video-assisted thoracoscopic surgery: a randomized, controlled, double-blind study.
Research has shown that a higher dose of bupivacaine administered in continuous paravertebral block (CPVB) provides a greater analgesic effect after video-assisted thoracoscopic surgery (VATS). In this randomized, controlled, double-blind study, we hypothesized that 0.25% 8 ml/h of levobupivacaine administered in CPVB after VATS provides a greater analgesic effect than 0.125% 8 ml/h. ⋯ UMIN000037930.

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.

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.

Predictive factors for favorable short-term response to interlaminar epidural block for cervical radiculopathy.
We sought to identify clinical predictors of favorable short-term outcomes associated with cervical interlaminar epidural injection (CIEI). Previous studies investigating the predictive factors of CIEI efficacy have shown inconsistent results. Gaining information on the possible response determinants of CIEI is necessary for appropriate treatment selection and outcomes prediction in the treatment of cervical radiculopathy. ⋯ CIEI provides a significant short-term outcome in patients with cervical radiculopathy. However, CIEI efficacy may be negatively affected in patients with spinal stenosis, the presence of a chronic state, and a possible neuropathic pain component.

Characteristics of retained foreign bodies and near-miss events in the operating room: a ten-year experience at one institution.
Retained foreign bodies (RFBs) are a major complication of surgical procedures. However, the efficacy of preventive measures is not well defined. This study investigates the characteristics of potential (near miss) and actual RFBs, and the contributions of routine practice for the prevention of RFB events. ⋯ The actual incidence of RFB events is higher than previously reported. A standardized counting protocol, communication among staff, and intra- and postoperative X-rays may contribute to the prevention and detection of RFBs.
