Opioid-tolerant individuals have greater risk of perioperative complications and worse clinical outcomes. A preoperative screening process and structured approach to opioid-tolerant patients was developed to identify and optimize these patients before elective surgery.

Case Reports
Transforaminal Sacral Nerve Neurostimulation for the Treatment of Intractable Chronic Pelvic Pain: Case Report.
This article aims to report the successful treatment of 2 patients with intractable chronic pelvic pain treated with transforaminal sacral nerve neurostimulation. At 18-month follow-up, both patients reported significant pain relief and improved performance. ⋯ In both reported cases, it proved to be useful for pain management. This technique should be evaluated in clinical trials.

We report for the first time therapy-resistant hypernatremia (plasma sodium concentration ≥150 mmol per liter) developing in 6 of 12 critically ill coronavirus disease 2019 (COVID-19) patients age 57-84 years requiring mechanical ventilation. There was no correlation between plasma sodium concentrations and sodium input. ⋯ These findings are consistent with abnormally increased renal sodium reabsorption, possibly caused by increased angiotensin II activity secondary to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced downregulation of angiotensin-converting enzyme 2 (ACE2) receptors. As hypernatremia was associated with increased length of intensive care unit stay, special attention should be paid to the electrolyte status of COVID-19 patients.

Case Reports
Ultrasound-Guided Selective Trunk Block to Produce Surgical Anesthesia of the Whole Upper Extremity: A Case Report.
None of the classical brachial plexus block techniques can reliably produce surgical anesthesia of the whole upper extremity that is from shoulder to hand. We describe ultrasound-guided "selective trunk block" (SeTB) that was successfully used to produce surgical anesthesia of the whole ipsilateral upper extremity in a patient undergoing intramedullary nailing of the humerus for a pathological fracture. The 3 trunks of the brachial plexus were individually identified and selectively blocked with 2 separate injections. We conclude that SeTB is a viable option when surgical anesthesia of the whole upper extremity, except for the intercostobrachial nerve (T2) territory, is being considered.

We describe a patient with an intrathecal drug delivery system (IDDS) for management of chronic back pain who developed worsening pain symptoms associated with an infected catheter tip, identified years after initial implantation. A 72-year-old woman had an IDDS initially implanted for management of chronic back pain. ⋯ Her pain worsened, and after explantation of the IDDS, methicillin-resistant Staphylococcus aureus colonized the catheter tip. Worsening pain symptoms in a patient with intrathecal morphine pump must be met with a broad differential diagnosis.
