The most common finding was a referral to those expressing pain related to endometriosis as "changuería" or "changas", terms used in Puerto Rico to describe pointless whining and complaining, often directed at children. References

This evidence suggests that PION is a disease of multifactorial origin.Risks of perioperative PION can be divided into two categories, intraoperative ischemic pressures, and cardiovascular risk factors. Intraoperative ischemic pressures
Many causes of decreased blood flow during surgery are systemic, i.e. they decrease blood flow throughout the body. Studies have shown that nearly all perioperative PION patients had prolonged periods of low blood pressure during the operation and postoperative anemia. The average perioperative PION patient loses 4 liters of blood during surgery, and the majority receive blood transfusions. Massive blood loss is just one cause of low blood pressure. Medications used for general anesthesia can also lower blood pressure. The average surgery duration in PION cases is 7 to 9 hours, which increases the risk of prolonged low blood pressure.Other intraoperative ischemic pressures are local, i.e. they decrease blood flow to the affected area, the optic nerve. Facial swelling, periorbital swelling, direct orbital compression, facedown position during surgery, and a tilted operating table in feet-above-head position, have all been reported to be associated with perioperative PION. All of these factors are believed to increase tissue pressure and venous pressure around the optic nerve, thereby decreasing local blood flow and oxygen delivery.Surgeries with the highest estimated incidence of PION are surgeries with a higher risk of the aforementioned conditions. In spine surgery, patients are susceptible to significant blood loss, and they are positioned face down for long periods of time, which increases venous pressure, decreases arterial perfusion pressure, and often causes facial swelling (increased tissue pressure).
