RESUMEN
Objective: To construct and validate nomogram models that predict the incidence of delirium in elderly patients with non-severe SARS-CoV-2 infection. Methods: Elderly patients (≥65y) tested positive for SARS-CoV-2 infection at the hospital were included. We used the 3-min diagnostic Confusion Assessment Method for delirium diagnosis. Least absolute shrinkage and selection operator (LASSO) logistical regression analysis was performed to explore potential independent influencing factors of delirium. A predict model visualized by nomogram was constructed based on the confirmed variables. The predictive accuracy and clinical value of the model were evaluated using receiver operating characteristic (ROC) curves. Results: The data of 311 elderly patients were analyzed, of whom 73 (23.47%) patients were diagnosed with delirium. Three independent influencing factors of delirium were confirmed: age (OR1.16,1.11-1.22), Glomerular filtration rate (OR 0.98,0.97-0.99), platelet-large cell ratio (1.06,1.02-1.10). These parameters were used to create a nomogram to predict the development of delirium, which showed good predictive accuracy confirmed by the ROC curves (AUC 0.82,0.76-0.88). Conclusion: We construct a credible nomogram to predict the development of delirium in elderly patients with Non-severe SARS-CoV-2 infection. Our finding may be useful to physicians in early prevention and treatment of delirium.
RESUMEN
OBJECTIVE: To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on the quality of recovery during the early period after laparoscopic cholecystectomy and the dosage of anesthetic and analgesic. METHODS: One hundred patients who received laparoscopic cholecystectomy with gradeâ and â ¡ of American Society of Anesthesiologists (ASA) criteria were randomly assigned into an observation group and a control group according to random number table, 50 cases in each group. The patients in the two groups were treated with conventional endotracheal intubation anesthesia, anesthesia induction and maintenance. The patients in the observation group were treated with TEAS (2 Hz/100 Hz, 8 to 12 mA) at bilateral Hegu (LI 4) and Neiguan (PC 6), as well as Zusanli (ST 36) and the non-acupoint 2 cun outboard from Zusanli (ST 36) from 30 min before anesthesia induction to the end of operation. The patients in the control group were applied by stimulation electrode in the corresponding points without electrical stimulation. The dosage of intraoperative remifentanil and the analgesic dosage of dezocine for postoperation were recorded. The recovery time, extubation time, the changes of heart rate (HR) and mean arterial pressure (MAP) during extubation were recorded. The quality of recovery was assessed by the quality of recovery-40 questionnaire (QoR-40) 1 day before surgery (T0)ï¼and 4 h (T1), 8 h (T2), 24 h (T3), 48 h (T4) after surgery. The patient's cognitive function was assessed by mini-mental state examination (MMSE) scale at the 5 time points. The incidences of postoperative nausea and vomiting were recorded at T1 through T4. RESULTS: The dosages of intraoperative remifentanil and dezocine in the observation group were less than those in the control group; the recovery time and extubation time were shorter than those in the control group; the HR of extubation was lower than that in the control group (all P<0.05). There was no statistic difference about MAP between the two groups (P>0.05). Compared with T0, the total scores of QoR-40 decreased in the two groups at T1, T2, T3 (all P<0.05), and the total scores in the observation group were higher than those in the control group (all P<0.05). The emotional state, physical comfort, psychological support, self-care ability, pain scores at T1 in the observation group and at T1, T2, T3 in the control group were lower than those at T0 (all P<0.05). The emotional state, physical comfort, psychological support, self-care ability, pain scores in the observation group were higher than those in the control group at T1, T2, T3 (all P<0.05). Compared with T0, the MMSE scores in the two groups decreased at T1 and T2 (all P<0.05). At T1, T2, T3, the MMSE scores in the observation group were higher than those in the control group (all P<0.05). At T1 and T2, the incidence rates of nausea and vomiting were 22.0% (11/50), 12.0% (6/50) respectively in the observation group, which were lower than 32.0% (16/50) and 24.0% (12/50) in the control group (both P<0.05). At T3 and T4, the incidence rates of nausea and vomiting were 6.0% (3/50), 2.0% (1/50) respectively in the observation group, which were not significantly different from 8.0% (4/50) and 4.0% (2/50) in the control group (both P>0.05). CONCLUSION: TEAS can improve the quality of recovery during the early period after laparoscopic cholecystectomy and reduce the dosage of anesthetic and analgesic.

Ultrasound-guided interscalene brachial plexus blockade (IBPB) has a relatively high success rate in shoulder surgery; however, whether multiple injections are superior to a single injection (SI) is currently unknown. In the present study, ultrasound-guided SI and triple-injection (TI) IBPBs were compared in a prospective randomized trial. A total of 111 patients undergoing arthroscopic shoulder surgery and presenting with an American Society of Anesthesiologists physical status grading of I-II were randomly allocated to receive IBPB with 15 ml of 1% ropivacaine as a SI or TI. Performance time, procedure-related pain scores, success rate and prevalence of complications were recorded. The distribution of sensory and motor block onset in the radial, median, ulnar and axillary nerves were assessed every 5 min until 30 min post-local anesthetic injection. The duration of sensory and motor blocks were also assessed. A significantly longer performance time was recorded in the TI group (P<0.001). No significant difference was observed in success rate (91% in TI vs. 88% in SI) 30 min post-injection, and the prevalence of complications and procedure-related pain were similar between the two groups. Sensory and motor blocks of the ulnar nerve in the TI group were significantly faster and more successful compared with the SI group at all time points (P<0.041). It was also observed that sensory and motor blocks in the TI group were prolonged compared with the SI group (P<0.041). In conclusion, the TI method exhibited a faster time of onset and resulted in a more successful blockade of the ulnar nerve. TI method may be a more effective approach for IBPB in a clinical setting.
