Oral carbohydrate solution cause an inflammatory response when aspirated into the lungs in mice.
Many studies have been published on the beneficial effects of oral carbohydrate solutions (OCS) administered prior to surgery. However, the risk of pulmonary aspiration cannot be excluded in all patients undergoing anesthesia. But, there are few studies on the safety of OCS at lung aspiration. ⋯ Aspiration of OCS may cause inflammation of the lungs. The preoperative use of OCS may require caution under specific clinical conditions, such as patients at risk of lung aspiration.

ReviewPredicting cardiac risk in noncardiac surgery: a narrative review.
Risk stratification endeavors to categorize patients into groups based on the level of risk for each group. Improved perioperative screening tests using more sensitive cardiac biomarkers have revealed that about 68% of perioperative myocardial infarctions (MI) are asymptomatic and may only be detected by routine postoperative screening with troponin measurements. This is important since myocardial injury not meeting criteria for myocardial infarction is associated with increased risk of 30-day mortality (Botto et al. in Anesthesiology 120:564-578, 2014). ⋯ Incorporating serum biomarkers into updated clinical risk indices is likely to improve their performance. Further studies are needed to determine appropriate clinical interventions to treat isolated elevations in cardiac troponin levels and further mitigate the increased risk of morbidity and mortality. The objective of this review is to summarize the current literature on the clinical diagnoses of perioperative myocardial injury in the setting of noncardiac surgery.

Randomized Controlled TrialErector spinae plane block versus retrolaminar block for postoperative analgesia after breast surgery: a randomized controlled trial.
The newly introduced erector spinae plane block (ESPB) has given anesthesiologists an alternative regional anesthetic technique for thoracic analgesia. Although ESPB and retrolaminar block (RLB) have similar puncture sites, no clinical study comparing ESPB and RLB has been reported. The aim of this study was to compare ESPB and RLB in terms of analgesic efficacy in the context of multimodal analgesia following breast surgery. ⋯ ESPB is equivalent, and not superior, to RLB for postoperative analgesia after breast surgery when 20 mL of 0.375% levobupivacaine is injected at the fourth thoracic vertebra.

Anatomical basis of erector spinae plane block: a dissection and histotopographic pilot study.
Erector spinae plane (ESP) block is an interfascial blockade used in different clinical scenarios. This study investigated the ventral extent of dye diffusion in ESP block. ⋯ The anterior pathway of dye diffusion from the site of injection within the erector spinae muscle group during an ESP block seems to follow the blood vessels and dorsal rami of spinal nerves, suggesting the passing through the costotransverse foramen to reach the anterior paravertebral space and the intercostal nerves. These findings display an anterior histotopographic diffusion of dye resembling a paravertebral block.

Validation of the Japanese version of the Bath CRPS Body Perception Disturbance Scale for CRPS.
Body perception disturbance is a common symptom and may be one of the key targets of treatment intervention in complex regional pain syndrome (CRPS). As a comprehensive assessment tool of body perception in patients with CRPS, the Bath Body Perception Disturbance Scale (BPDS) was developed, and its adequate reliability and validity have been reported. However, there is no available Japanese version. Therefore, this study aimed to develop a Japanese version of BPDS (BPDS-J) and to investigate the validity of this scale in Japanese patients with CRPS. ⋯ BPDS-J has good internal consistency and concurrent validity for assessing body perception disturbance in Japanese patients with CRPS. Disturbed body perception may be worth evaluating when managing patients with CRPS using BPDS.
