    Abstract: Established conventional treatments for postherpetic neuralgia (PHN) and postherpetic itch (PHI) are difficult and often disappointing. In this study, the authors investigated the effect and mechanisms of extracorporeal shockwave therapy (ESWT) on pain and itch associated with PHN and PHI. Thirteen patients, 50 to 80 years of age, with symptoms associated with PHN or PHI (duration of persistent pain 〉 3 months) and complaints of pain or itch rated 〉 4 on a numerical rating scale (NRS), were included. ESWT was administered using a shockwave device (Piezo Shockwave 2 , Richard Wolf GmbH, Knittlingen, Germany) to skin areas affected by pain or itch. An energy flux density of 0.09 to 0.16 mJ/mm 2 at a frequency of 5 Hz and 2000 impulses was administered at 3-day intervals for 6 sessions. The NRS, 5D-Itch Scale, and Patients Global Impression of Change (PGIC) scale were used to evaluate the efficacy of ESWT. NRS scores of pain and itch and 5D-Itch Scale scores decreased significantly compared with before treatment and at the end of the treatment sessions ( P   〈  .0001, P  = .001, P  = .0002, respectively). There was a statistically significant difference between PGIC scores, which were checked every 2 sessions ( P   〈  .0001). ESWT is a noninvasive modality that significantly reduced PHN-associated pain and itch.

    Abstract: This study aimed to compare gastric ultrasound assessments between young and elderly patients, to determine whether the cross-section area (CSA) cutoff values for elderly and young patients should be different, and to suggest CSA cutoff values for elderly patients. This study evaluated the data of 120 patients who underwent elective surgery under general anesthesia between July 2019 and August 2020. Demographic and gastric ultrasound assessment data were retrieved. Patients were divided into the elderly group (n = 58, age: ≥65 years) and young group (n = 62, age: 〈 65 years). The CSAs in the supine and right lateral decubitus positions (RLDP), semiquantitative 3-point Perlas grade (grades 0, 1, and 2), and gastric volume (GV) were determined. CSAs according to different Perlas grades were compared between the 2 groups. To compare normally and non-normally distributed continuous data, Student t test and the Mann–Whitney U test were used, respectively. Categorical data were compared using the chi-square test or Fisher exact test, as appropriate. The receiver operating characteristic (ROC) curves were built for the CSAs to predict pulmonary aspiration. The CSA cutoff values for predicting a high risk of pulmonary aspiration in both the groups were determined. Among patients with Perlas grade 0, the CSA supine ( P  = .002) and CSA RLDP ( P  = .002) were greater in the elderly group than in the young group. The specificity, positive predictive value, and accuracy of the CSA decreased when the CSA cutoff value for the young group was applied to the elderly group. The CSA cutoff values for the elderly group were: CSA supine , 6.92 cm 2 and CSA RLDP , 10.65 cm 2 . The CSA of the empty stomach was greater in elderly patients than in young patients. We suggest that the following CSA cutoff values should be used for predicting pulmonary aspiration risk in elderly patients: CSA supine , 6.92 cm 2 and CSA RLDP , 10.65 cm 2 .

    Abstract: Tools for the evaluation of gastric emptying have evolved over time. The purpose of this study was to show that the risk of pulmonary aspiration is not increased with carbohydrate drink, by demonstrating that the gastric antral cross-sectional area (CSA) of the NO-NPO group is either equivalent to or less than that of the NPO (nil per os) group. METHODS: Sixty-four patients scheduled for elective laparoscopic benign gynecologic surgery were enrolled and randomly assigned to the NPO group (n = 32) or the NO-NPO group (n = 32). After having a regular meal until midnight before surgery, the NPO group fasted until surgery, while the NO-NPO group ingested 400 mL of a carbohydrate drink at midnight and freely up to 2 hours before anesthesia. The primary outcome was the gastric antral CSA by gastric ultrasound in right lateral decubitus position (RLDP). Noninferiority was defined as a mean difference of CSA 〈 2.8 cm 2 . Secondary outcomes included CSA in supine position, gastric volume (GV), GV per weight (GV/kg), GV/kg 〉 1.5 mL/kg, and Perlas grade. RESULTS: CSA in RLDP was not different between the NPO group (6.25 ± 3.79 cm 2 ) and the NO-NPO group (6.21 ± 2.48 cm 2 ; P = .959). The mean difference of CSA in RLDP (NO-NPO group − NPO group) was 0.04 (95% confidence interval [CI], −1.56 to 1.64), which was within the noninferiority margin of 2.8 cm 2 . CSA was not different between the 2 groups (4.17 ± 2.34 cm 2 in NPO group versus 4.28 ± 1.23 cm 2 in NO-NPO group; P = .828). GV in NPO group (70 ± 56 mL) was not different from NO-NPO group (66 ± 36 mL; mean difference, 3.66; 95% CI, −20 to 27; P = .756). GV/kg in the NPO group (1.25 ± 1.00 mL/kg) was not different from the NO-NPO group (1.17 ± 0.67 mL/kg; P = .694). The incidence of GV/kg 〉 1.5 mL/kg was not different between NPO (31.3%) and NO-NPO group (21.9%; P = .768). The median (interquartile range) of the Perlas grade was 1 (0–1) in NPO group and 0.5 (0–1) in NO-NPO group ( P = .871). CONCLUSIONS: Preoperative carbohydrates ingested up to 2 hours before anesthesia do not delay gastric emptying compared to midnight fasting, as evaluated with gastric ultrasound.

    Abstract: Preoperative carbohydrate loading enhances postoperative recovery and reduces patient discomfort. However, gastric emptying of liquids can be delayed in elderly populations. Therefore, this study aimed to evaluate the gastric emptying of 400 mL of a carbohydrate drink ingested 2 hours before surgery in elderly patients. Methods: In this prospective, randomized controlled study, patients aged 〉 65 years were allocated to either fast from midnight (nil per os [NPO] group, n = 29) or drink 400 mL of a carbohydrate drink 2 hours before surgery (carbohydrate group, n = 29). The gastric antrum was assessed using ultrasonography in the supine position, followed by the right lateral decubitus (RLD) position. The gastric antrum was graded as grade 0 (fluid not seen in both positions), grade 1 (fluid only seen in the RLD position), and grade 2 (fluid seen in both positions). The gastric antral cross-sectional area (CSA) and aspirated residual gastric volume were measured. Results: In 58 patients, the incidence of grade 2 stomach was 13.8% in NPO group and 17.2% in carbohydrate group ( P  = .790). The gastric antral CSA in the supine position was larger in carbohydrate group than in NPO group (4.42 [3.72–5.18] cm 2 vs 5.31 [4.35–6.92] cm 2 , P  = .018). The gastric antral CSA in the RLD position was not different in NPO and carbohydrate groups ( P  = .120). There was no difference in gastric volume (2 [0–7.5] vs 3 [0–13.4] , P  = .331) in NPO group versus carbohydrate group. Conclusion: The incidence of grade 2 stomach was not different between NPO group and carbohydrate group in elderly patients.
