Introduction In this study, our objective was to compare the lateral sagittal infraclavicular block (LS-ICB) with the costoclavicular infraclavicular block (CC-ICB) for ultrasound (US)-guided infraclavicular brachial plexus block in terms of block dynamics as well as patient and surgeon satisfaction levels. Methods A total of 100 patients, falling under the American Society of Anaesthesiologists (ASA) I-III categories, who were aged 18-65 years and scheduled for elective forearm and hand surgery were enrolled in the study. The patients were randomly allocated to receive a US-guided LS-ICB or US‑guided CC-ICB. The local anesthetic (LA) agent used (20-ml 0.5% bupivacaine) was identical in all subjects. The block performance time and the motor and sensory block onset times were determined to be the primary outcomes. FEN1-IN-4 price Results The block performance time and the sensory block onset time were shorter in the CC-ICB group compared to the LS-ICB group [median (interquartile range) three (2.5-3.3) vs. two (1.5-2.3) minutes, p less then 0.001; five (4.4-6) vs. four (3.8-6) minutes, p = 0.022, respectively]. The number of needle redirections was lower in the CC-ICB [three (2.7-4) vs. two (one to two) times, p less then 0.001]. The motor block onset time and the motor-sensory block times were similar in both groups. There were more patients with a complete sensory blockade at five and 10 minutes in the CC-ICB group than in the LS-ICB group (30% vs. 12%, p = 0.027; 66% vs. 26%, p less then 0.001, respectively). No complications were observed with regard to both techniques, and patient and surgeon satisfaction levels observed were similar for both groups. Conclusion Based on our findings, the CC approach provided a shorter performance time and a faster onset of the sensory block compared to the LS approach. However, no complications were reported with respect to either technique, and similar patient and surgeon satisfaction levels were observed.Background Few studies have assessed the relationship between serum total carbon dioxide (CO2) and bicarbonate ion (HCO3 -) concentration in patients undergoing peritoneal dialysis. We determined the agreement between serum total CO2 and HCO3 - concentration and the diagnostic accuracy of serum total CO2 for the prediction of low (HCO3 - less then 24 mEq/L) and high (HCO3 - ≥24 mEq/L) bicarbonate concentrations in patients on peritoneal dialysis. Methods We collected 245 samples of venous blood from 51 patients on peritoneal dialysis. Independent factors that correlated with the HCO3 - concentration were analyzed using multiple linear regression analysis. The diagnostic accuracy of serum total CO2 was evaluated by receiver operating characteristic (ROC) curve analysis and a 2×2 table. Agreement between serum total CO2 and HCO3 - concentration was assessed by Bland-Altman analysis. Results Serum total CO2 was independently correlated with HCO3 - concentration (β = 0.354, p less then 0.001). The area under the curve of serum total CO2 for the identification of low and high bicarbonate concentrations was 0.909. The diagnostic accuracy of serum total CO2 for the prediction of low and high bicarbonate concentrations was sensitivity, 91.5%; specificity, 74.7%; positive predictive value, 53.5%; negative predictive value, 96.5%; and accuracy, 78.8%. Bland-Altman analysis showed a moderate agreement between serum total CO2 and HCO3 - concentration. Conclusion Serum total CO2 correlated closely with the HCO3 - concentration in patients undergoing peritoneal dialysis. Serum total CO2 might be useful for predicting low and high bicarbonate in peritoneal dialysis patients.[This retracts the article DOI 10.1177/2164956119831221.].Mobile mental health interventions have the potential to reduce barriers and increase engagement in psychotherapy.
