Background: The placenta accreta spectrum (PAS) is a severe complication of pregnancy and is associated with massive haemorrhage, hysterectomy, and even perinatal maternal-foetal death. Prophylactic abdominal aortic balloon occlusion (PAABO) is a novel and efficient therapy for these patients. The aim of this study was to investigate the benefits, potential risks, and characteristics of anaesthesia management. Methods: A total of 48 parturients with PAS were enrolled and divided into two groups. Group A (n = 25) received PAABO, and Group B (n = 23) underwent a normal operative procedure. The characteristics of the general parameters, anaesthesia, and operative procedure were noted. Data on vital signs including systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) during the operation were recorded. Before and after the procedure, hepatic and renal function and lactate dehydrogenase (LDH) were also measured. Results: The characteristics of the groups were comparable. PAABO significantly reduced estimated blood loss, which was ≥ 1000 ml. Drastic fluctuations in SBP, DBP and HR were observed during inflation and deflation in Group B. After the operation, increased LDH and glutamic oxaloacetic transaminase (GOT) were observed in both groups, and increased glutamic-pyruvic transaminase (GTP) was observed in Group B. Conclusions: PAABO reduced perioperative blood loss and the risk of hysterectomy among parturients with PAS. Sophisticated anaesthetic management should be implemented to prevent or reduce perioperative complications and address internal disorders that are caused by massive blood loss.

The effect of super atmospheric O2 packaging on the quality and physiological character of cherry fruits in Wenchuan County in Sichuan province was investigated at 4C and at a relative humidity of 70 ± 1%. The results showed that, compared with control (air packaging), super atmospheric O2 packaging effectively delayed the respiration peak of cherry fruits, markedly inhibited (P < 0.05) ethylene production for the first 4 days of storage, effectively maintained firmness and soluble protein and sugar contents, and significantly delayed (P < 0.05) the increase of polyphenol oxidase and peroxidase activities except for days 2 and 8 of storage. However, the vitamin C contents of cherry fruits packaged by super atmospheric O2 declined much more than control. Therefore, combined with the technique of vitamin C protection, super atmospheric O2 packaging will be a prospective way to extend the postharvest quality of cherry fruits. Practical Applications Cherry fruits usually have a short shelf life because of quality deterioration. In this study, super atmospheric O2 packaging effectively inhibited the respiration of cherry fruits, maintained firmness and soluble protein and sugar contents, and significantly reduced polyphenol oxidase and peroxidase activities. If combined with the technique of vitamin C protection, super atmospheric O2 packaging will be a prospective way to extend postharvest quality of cherry fruits in the future.
