Platypnoea-Orthodeoxia Syndrome is an uncommon phenomenon characterized by dyspnea/arterial desaturation in the standing position, resolving in recumbency. Some patients present with Platypnoea-Orthodeoxia Syndrome in the early-or-late post-operative period after major lung resection (lobectomy/pneumonectomy). The main cause of Platypnoea-Orthodeoxia Syndrome is an intracardiac anomaly (Patent Foramen Ovalis/Atrial Septal Defect) leading to right-to-left shunt. ⋯ Platypnoea-Orthodeoxia Syndrome after lobectomy is a rare cause of post-operative dyspnea/hypoxia. It is the result of right-to-left shunt via an interatrial communication. Mediastinal relocation, stretching of the atrial septum and aortic root dilatation are among the functional elements necessary for the Platypnoea-Orthodeoxia Syndrome manifestation.

Objective: Recently, there has been an increasing interest in combined adductor canal block (ACB) with periarticular anesthetic injection (PAI) as a technique to control postoperative pain in total knee arthroplasty (TKA). This study evaluated the analgesic efficacy and safety of the combined therapy for early postoperative pain treatment after TKA. Methods: From the inception to July 2018, two independent investigators used the following electronic databases to search existing literature: PubMed, Embase, Medline, and Web of Science. ⋯ Similarly, there were no significant differences between groups in opioid-related adverse effects, and LOS. Conclusions: There is evidence that combined therapy is more effective than single therapy within 48 h following primary TKA. Applying combined therapy appears to be an effective and safe method for pain control.
