ReviewPatient controlled epidural analgesia during labor: Protocol for a scoping review.
Childbirth remains one of the most painful experiences for women. Patient-controlled epidural analgesia provides the women in labor with self-control and thereby a shorter time interval between onset of pain and administration of analgesia, thus potentially improving the childbirth experience. This scoping review aims to investigate PCEA during labor involving maternal satisfaction, risks of adverse effects and obstetric interventions by mapping the evidence and identifying gaps in the current evidence base. ⋯ PCEA offers women greater autonomy during childbirth, making it essential to examine its effects and potential risks. By mapping current evidence regarding PCEA, this review aims to identify knowledge gaps and provide insights to enhance maternal care and improve childbirth experiences.

Accuracy of estimating equations for the assessment of glomerular filtration rate in critically ill patients versus outpatients.
Estimating equations for the assessment of glomerular filtration rate (GFR) have been poorly investigated in the critical care setting. We evaluated the agreement between the GFR measured with 51CrEDTA/iohexol (mGFR) and four estimating equations based on serum concentrations of creatine and/or cystatin C (eGFR) in two cohorts: critically ill patients and outpatients with normal-to-moderately reduced GFR. ⋯ For the assessment of glomerular filtration rate (GFR), it can be measured directly, but is frequently estimated using a point measure of serum creatinine concentration. In this study, ICU case GFR estimations, by different adjusted equations, done also for a cohort of outpatients, showed that these serum creatinine-based estimations for ICU cases are not highly precise or reliable.

Comparative StudyComparison of venous and calculated blood gas values to arterial values in critically ill patients.
Arterial blood gas (ABG) values are important in the assessment of critically ill patients. However, arterial puncture may be challenging to perform in these patients. The venous-to-arterial conversion method (v-TAC) is used to convert venous blood gas values to calculated values meant to resemble arterial values. Calculated pH and partial pressure of carbon dioxide (PCO2) values have shown good agreement with arterial values in stable patients, but performance of the method in patients with severe acid-base disturbances is unknown. We aim to evaluate venous and calculated blood gas value congruency with arterial values in critically ill patients. ⋯ Venous and calculated pH and PCO2 values showed similar congruency with arterial values in patients with alkalemia and moderate acidaemia, while the method was unreliable in a patient suspected of severe metabolic acidaemia.
