Several studies explored the interdependence between Paco2 and bicarbonate during respiratory acid-base derangements. The authors aimed to reframe the bicarbonate adaptation to respiratory disorders according to the physical-chemical approach, hypothesizing that (1) bicarbonate concentration during respiratory derangements is associated with strong ion difference; and (2) during acute respiratory disorders, strong ion difference changes are not associated with standard base excess. ⋯ The bicarbonate adaptation that follows primary respiratory alterations is associated with variations of strong ion difference. In the acute phase, the variation in strong ion difference is mainly due to sodium variations and is not paralleled by modifications of standard base excess. In the chronic setting, strong ion difference changes are due to chloride variations and are mirrored by standard base excess.

Patient Satisfaction With, and Outcomes of, Ultrasound-Guided Regional Anesthesia at a Referral Hospital in Tanzania: A Cross-Sectional Study.
Regional anesthesia techniques are increasingly used in high-income countries (HICs) for both surgical anesthesia and postoperative analgesia. However, regional anesthesia has not been utilized to the same degree in low- to middle-income countries (LMICs) due to a lack of resources and trained personnel. This study evaluates patient satisfaction with, and outcomes of, ultrasound-guided regional anesthesia for extremity surgery at Kilimanjaro Christian Medical Center (KCMC) in the Northeastern zone of Tanzania. ⋯ Our study found that ultrasound-guided regional anesthesia in a resource-constrained setting was effective for extremity surgery and resulted in high patient satisfaction. No complications occurred. The use of ultrasound-guided regional anesthesia shows promise for the safe and effective care of patients undergoing extremity surgery in LMICs.

Early exposure to neurosurgery during medical school is critical to improving recruitment into the specialty. About 30% of medical schools in the U. S. lack a home program in neurosurgery, thereby, limiting their exposure to the field of neurosurgery. ⋯ We identified 16 resources through a database search and through popular social media platforms. Nine out of 16 resources were video based, and 2 utilized the concept of spaced repetition through flashcards. Our review describes these educational resources and aims to serve as a guide for medical students interested in neurosurgery.

In previous analyses, myocardial injury after noncardiac surgery, major bleeding, and sepsis were independently associated with most deaths in the 30 days after noncardiac surgery, but most of these deaths occurred during the index hospitalization for surgery. The authors set out to describe outcomes after discharge from hospital up to 1 yr after inpatient noncardiac surgery and associations between predischarge complications and postdischarge death up to 1 yr after surgery. ⋯ One in 18 patients 45 yr old or older discharged after inpatient noncardiac surgery died within 1 yr, and one quarter were readmitted to the hospital. The risk of death associated with predischarge perioperative complications persists for weeks to months after discharge.

People with complex regional pain syndrome (CRPS) commonly report a fear of movement that can worsen symptoms and increase disability. The Tampa Scale of Kinesiophobia (TSK) is used to evaluate fear of movement and (re)injury, but findings have been inconsistent in different populations. ⋯ The TSK-11 demonstrates excellent retest reliability in people with CRPS. The original 2-factor structure was not confirmed, and a new 2-factor structure of the TSK-11 was proposed consisting of subscales for Fear Avoidance Beliefs and Magnification/Helplessness. Given the overlap between these constructs and the construct of pain catastrophizing, further study is needed to clarify both measures' content validity and relative uniqueness.
