Performance of Shock Index as a predictor of severe postpartum hemorrhage following cesarean section under spinal anesthesia: a retrospective cohort study.

Background: An early diagnosis of a postpartum hemorrhage (PPH) can be challenging. The Shock Index (SI), the ratio of heart rate to systolic blood pressure, appears to be a useful indicator for the early diagnosis of severe PPH after vaginal delivery. Our primary aim was to evaluate if the SI has a predictive value for severe PPH following cesarean section (C-section) under spinal anesthesia (SA) and its best predictive threshold.

Maternal heart rate responses in the supine position and their relationship with hypotension and phenylephrine requirements during elective caesarean delivery using spinal anaesthesia: An observational study.

Background: Hypotension is the main side effect of spinal anaesthesia (SA) for elective caesarean delivery (CD). An increased in heart rate in response to inferior vena cava (IVC) compression has been reported to be predictive of hypotension and vasopressor requirements in this setting. The objective of the study was to evaluate the prevalence of an increase in heart rate in response to IVC compression and its potential effect on hypotension and phenylephrine requirements.

[Tungiasis, an uncommon ectoparisitic disease].

Tungiasis is an infestation of the skin due to the sand flea chigger (or Tunga penetrans). After penetration under the nails of the feet, this ectoparasite enlarged and the lesion becomes painful. Diagnosis is made on the past history (travel in tropical areas) and the inspection.
