Perioperative Management of Parturient Women With Severe Pulmonary Arterial Hypertension Secondary to Atrial Septal Defect.

At our institution, we occasionally see pregnant patients in the later stages of pregnancy who present with severe pulmonary arterial hypertension caused by congenital heart disease. The physiological changes in pregnancy may worsen the cardiovascular status leading to heart failure which is associated with a high incidence of morbidity and mortality. A scheduled caesarean section in such patients ensures delivery in a controlled environment, avoiding prolonged labour, which is detrimental.

Performance of Point-of-Care Ultrasonography in Confirming Feeding Tube Placement in Mechanically Ventilated Patients.

Background: A feeding tube (FT) is routinely placed in critically ill patients, and its correct placement is confirmed with a chest X-ray (CXR), which is considered the gold standard. This study evaluated the diagnostic accuracy of ultrasonography (USG) in verifying FT placement compared to a CXR in an intensive care unit (ICU).

Method: This was a prospective single-blind study conducted on patients admitted to the ICU of a tertiary hospital in Malaysia.

Intraoperative phenylephrine infusion to reduce perioperative shivering in lower segment caesarean section: A randomised controlled study.

Background: Shivering is described as an involuntary, repetitive activity of the skeletal muscles that can have deleterious effects on anaesthetized patients. This study aimed to evaluate the effectiveness of phenylephrine infusion in preventing perioperative shivering in patients undergoing lower segment cesarean section under spinal anesthesia and to observe the change in the patient's core temperature between the study and control groups.

Methods: A total of 118 patients scheduled for elective lower segment cesarean section under spinal anesthesia were recruited for this prospective, double-blind, randomized controlled study.

Analgesic efficacy of the superficial versus deep serratus plane blocks for mastectomy with axillary clearance: A randomized controlled trial.

Background: The serratus plane block is an effective technique for providing analgesia to patients undergoing breast surgery.

Methods: This prospective, double-blind, randomized study enrolled 60 female patients scheduled for unilateral mastectomy and axillary clearance. The patients received either a superficial serratus plane block or deep serratus plane block.
