Platypnea orthodeoxia syndrome (POS) is a rare cause of hypoxemia. Diagnosis of POS is challenging, requiring a high index of clinical suspicion, special investigations, and collaboration with multiple specialists. ⋯ Platypnea orthodeoxia syndrome is a rare presentation of hypoxemia. Positional changes in oxygenation are the cardinal feature of POS. Discordance between lung imaging and the severity of hypoxemia should prompt investigation for an intracardiac shunt, which can occur in POS even in the absence of increased right-sided heart pressures. Either contrast TTE or transesophageal echocardiography is necessary to make this diagnosis.

Comparative Study
Postoperative analgesic consumption for primary versus first repeat Cesarean delivery: a historical cohort study.
It is unclear if postoperative pain experience and opioid consumption differ in patients undergoing primary vs repeat Cesarean delivery (CD) as prior studies have yielded conflicting results and none used the same patients as their own controls. We sought to compare opioid consumption and pain scores in patients undergoing both a primary and a first repeat CD, using the same patients as their own controls. ⋯ In this retrospective study, we found no differences in postoperative opioid consumption or reported pain scores in patients who underwent both a primary and a first repeat CD.
