Non-inferiority randomized controlled trial comparing CricOid pressure and Para-laryngeal pressure in parturients undergoing cesarean delivery: NiCOP trial
Perioperative aspiration of gastric contents is one of the most dreaded complications of general anesthesia (GA). Owing to the anatomical, physiological and hormonal alterations during pregnancy, the parturient undergoing cesarean delivery (CD) with GA is at a higher risk of pulmonary aspiration.1 Pharmacological measures like non-particulate antacids, histamine H2-receptor antagonists and prokinetic drugs have been used to reduce the risk of this complication.2 (Source: International Journal of Obstetric Anesthesia)

Non-targeted serial epidural blood patching for the treatment of intracranial hypotension headache during late pregnancy: a case report
Intracranial hypotension can cause debilitating headaches, commonly due to the leakage of cerebrospinal fluid (CSF) through a spinal dural defect or a CSF-venous fistula.1 It can also occur spontaneously, at an estimated annual rate of 5 per 100 000.2 Although the most common presentation is orthostatic headaches,3 the symptoms can be non-specific and include nausea, neck stiffness, blurred vision, and various neurological deficits,1,4 sharing similarities with those of migraine.5 Therefore, the diagnosis of intracranial hypotension can be challenging and is often missed or delayed.

Disparities in postpartum readmission by patient- and hospital-level social risk factors in the United States: A retrospective multistate analysis, 2015-2020
The leading cause of hospital admission in the United States is related to pregnancy and delivery, accounting for nearly 4 million hospitalizations and costing $16.1 billion annually.1,2 Postpartum readmission following discharge from childbirth hospitalization has become a potential area of focus for improving the quality of obstetric care and reducing costs.3 However, unlike the United States Centers for Medicare& Medicaid Services ’ Hospital Readmissions Reduction Program (HRRP), which consists of six specific condition or procedure-related readmission measures primarily occurring among the older patient population, a...

Importance of the time sequence between measurement of the predictor and of the predicted outcome: response
We sincerely appreciate the insightful comments of Dr. Madar regarding our manuscript. Your suggestion regarding the importance of considering the time sequence between the predictor (shock index [SI]) and predicted outcome (postpartum hemorrhage [PPH]) is highly valuable. Madar et al. published a remarkable publication in the British Journal of Obstetrics and Gynaecology in 2023 evaluating the predictive ability of SI for PPH at 15 and 30 min after vaginal delivery using an analytical approach that considers the time sequence between SI and PPH (blood loss of ≥1,000 mL) [1].

Severe back labor pain masks a scald caused by shower hydrotherapy: a case report
We report a case of extensive scalds in a primigravida who used shower hydrotherapy to treat severe back labor pain from fetal malposition. Interestingly, her back pain was so severe that she felt no pain as her scald developed, describing the hot water from the showerhead as the only measure which “soothed” her pain. Her scald was diagnosed presumptively during assessment for epidural analgesia. The nature of her back labor pain, associated with occiput posterior fetal head position and her management are described. (Source: International Journal of Obstetric Anesthesia)

Severe back labor pain masks a scald caused by shower hydrotherapy – a case report
Hydrotherapy is one of the non-pharmacological modalities used for labor analgesia and is available as either immersion (tub) or shower hydrotherapy.1,2 The hydrokinetic and thermal effects of warm water are believed to promote muscle relaxation and local vasodilation, while stimulating the release of endorphins.3 By activating cutaneous thermo-receptors and mechano-receptors, hydrotherapy may block upward transmission of afferent labor pain fibers at the spinal cord, thereby altering labor pain perception.

Labour: a pain for informed consent?
Legally, valid consent in England and Wales requires the patient to receive information about reasonable alternative treatments, in a way which is intelligible to them.1 It is perhaps ironic that the obstetric surgery case that gave rise to this requirement, Montgomery, is yet to be realised in obstetric anaesthesia.

Variability of fibrinolytic activity in pregnant patients exposed to tissue plasminogen activator: an in vitro study utilizing rotational thromboelastometry
Fibrinolysis, the process of breaking down blood clots, plays a crucial role in maintaining hemostasis and preventing excessive clot formation.1 Following coagulation, tissue plasminogen activator (tPA) induces fibrinolysis by converting plasminogen to plasmin which enzymatically cleaves the fibrin clot into fibrin degradation products (FDPs).2 During pregnancy, the maternal fibrinolytic system must be appropriately regulated to accommodate the physiological demands of gestation. However, alterations in the delicate balance of fibrinolysis can occur, leading to conditions such as hyperfibrinolysis, characterized by excessi...

Lower-body warming and postoperative temperature in cesarean delivery under spinal anesthesia: a randomized controlled trial
Peri-operative hypothermia and shivering are common during and after cesarean delivery (CD) under spinal anesthesia. Hypothermia reportedly occurs in approximately 60% of cases, and is associated with surgical site infection, cardiac complications and coagluopathies.1 –5 Shivering, seen in approximately 85% of cases, not only causes discomfort but also introduces the potential for monitoring errors and increased oxygen consumption.6 (Source: International Journal of Obstetric Anesthesia)

Importance of the time sequence between measurement of the predictor and the predicted outcome
We congratulate Mizutani and colleagues for their insight on predictive performance of shock index (SI) for postpartum hemorrhage (PPH) during cesarean delivery, which provides an overview of the pattern of SI during cesarean delivery and explores its usefulness for detecting PPH.1 Nevertheless, we would like to emphasize the importance of distinguishing prediction from diagnosis of PPH. The title suggests that SI has been assessed as a predictor of PPH during cesarean delivery, however the methods and results indicate that the SI was analyzed as a detection-tool of PPH.

Management of sporadic intracranial vascular malformations in pregnancy: a retrospective analysis
With the increased availability of brain imaging, unruptured vascular malformations (VMs) are becoming more frequently diagnosed. Differentiating between significant and incidental findings becomes more challenging and influences management. In the general population, the estimated prevalence of arteriovenous malformations (AVMs), cavernous malformations (CVMs) and developmental venous anomalies (DVAs) is approximately 0.01 to 0.5%, 0.3 to 0.5%, and 2 to 3%, respectively.1,2 When looking specifically at parturients, Maor et.
