RESUMEN
BACKGROUND: Over the last decade, there has been an increasing awareness for the potential harm of the administration of too much oxygen. We aimed to describe self-reported attitudes towards oxygen therapy by clinicians from a large representative sample of intensive care units (ICUs) in the Netherlands. METHODS: In April 2019, 36 ICUs in the Netherlands were approached and asked to send out a questionnaire (59 questions) to their nursing and medical staff (ICU clinicians) eliciting self-reported behaviour and attitudes towards oxygen therapy in general and in specific ICU case scenarios. RESULTS: In total, 1361 ICU clinicians (71% nurses, 24% physicians) from 28 ICUs returned the questionnaire. Of responding ICU clinicians, 64% considered oxygen-induced lung injury to be a major concern. The majority of respondents considered a partial pressure of oxygen (PaO2) of 6-10 kPa (45-75 mmHg) and an arterial saturation (SaO2) of 85-90% as acceptable for 15 minutes, and a PaO2 7-10 kPa (53-75 mmHg) and SaO2 90-95% as acceptable for 24-48 hours in an acute respiratory distress syndrome (ARDS) patient. In most case scenarios, respondents reported not to change the fraction of inspired oxygen (FiO2) if SaO2 was 90-95% or PaO2 was 12 kPa (90 mmHg). CONCLUSION: A representative sample of ICU clinicians from the Netherlands were concerned about oxygen-induced lung injury, and reported that they preferred PaO2 and SaO2 targets in the lower physiological range and would adjust ventilation settings accordingly.

Three pregnant women, of whom 2 were 33 and 1 was 35 years of age, were seen; 2 of them had upper abdominal pain and 1had oedema. All had proteinuria and liver enzyme abnormalities, and pre-eclampsia or the HELLP syndrome was suspected. They were consequently admitted and at first treated with antihypertensive agents. One patient underwent a Caesarean section and the baby had a good start. Afterwards, however, the patient developed shock. A CT-scan revealed a hepatic rupture, for which repeated surgical packing of the liver was carried out. The postoperative course was complicated. A second patient developed shock and the foetus died. Here the CT-scan revealed a liver haematoma. At surgery the next day, removal of the foetus was followed by heavy uterine bleeding. The patient again developed shock and the uterus was resected. A haematoma that was seen in the liver was treated expectatively. The postoperative course was not complicated. In a third patient, abdominal echography revealed bleeding from the liver. Simultaneous Caesarean section and surgical exploration of the liver took place, with packing of the liver. The child had Apgar scores of 4, 7 and 9. After re-laparotomy because of persistent bleeding from the liver the patient recovered. Spontaneous liver haemorrhage and hepatic rupture during pregnancy is a rare condition associated with significant maternal and perinatal mortality. The majority of cases occur during pregnancies complicated by pre-eclampsia or the HELLP syndrome. The presenting symptoms are non-specific. A high index of suspicion is important and early evaluation with imaging is necessary to improve the prognosis of both mother and child.
