Comparison of phenylephrine and norepinephrine for prevention of hypotension in patients undergoing cesarean section under spinal anesthesia – A randomized prospective study

Journal of Obstetric Anaesthesia and Critical Care, 2022
Background: Hypotension is a common side effect of spinal anesthesia for cesarean section with incidence of upto 71%. Various vasopressors are available for counteracting spinal hypotension each with different pharmacological profile.

Phenylephrine as an alternative to cocaine for nasal vasoconstriction before nasal surgery: A randomised trial

Indian Journal of Anaesthesia, 2013
Background: Cocaine is often used topically to provide the profound vasoconstriction required for nasal surgery; however, it has been associated with intraoperative cardiac adverse effects.

Prophylactic Phenylephrine Increases the Dose Requirement of Oxytocin to Treat Uterine Atony During Cesarean Delivery: A Double-Blinded, Single-Center, Randomized and Placebo-Controlled Trial

Frontiers in Pharmacology, 2021
Purpose: Studies involving mouse models and human uterine smooth muscle cells have shown that phenylephrine inhibits uterine contractions in non-pregnant mice and human in vitro cell via cyclic adenosine monophosphate (cAMP) signaling. However, there has

Comparison of norepinephrine and phenylephrine boluses for the treatment of hypotension during spinal anaesthesia for caesarean section – A randomised controlled trial

Indian Journal of Anaesthesia, 2019
Background and Aims: Hypotension following spinal anaesthesia for caesarean section is common in spite of adequate fluid loading. Phenylephrine is the recommended drug to treat spinal hypotension during caesarean section. Recently, norepinephrine boluses

Efficacy of fixed-dose phenylephrine bolus for treating post-spinal hypotension: Comparison between pre-eclamptics and normotensives

Journal of Anaesthesiology Clinical Pharmacology, 2023
Background and Aims: Pre-eclamptic parturients may have an exaggerated response to vasopressors. This study compares the efficacy of a 50 μg fixed bolus of phenylephrine for treatment of post-spinal hypotension in pre-eclamptic versus normotensive ...

A Prospective, Randomized, Double-Blinded Study of the Effect of Intravenous Ondansetron on the Effective Dose in 50% of Subjects of Prophylactic Phenylephrine Infusions for Preventing Spinal Anesthesia–Induced Hypotension During Cesarean Delivery

Anesthesia and Analgesia, 2019
BACKGROUND: Ondansetron has been shown to reduce the incidence of hypotension and vasopressor requirement during spinal anesthesia for obstetric and nonobstetric surgery. However, the magnitude of this effect has not been fully quantified.

Phenylephrine increases cardiac output by raising cardiac preload in patients with anesthesia induced hypotension

Journal of clinical monitoring and computing, 2018
Induction of general anesthesia frequently induces arterial hypotension, which is often treated with a vasopressor, such as phenylephrine. As a pure α-agonist, phenylephrine is conventionally considered to solely induce arterial vasoconstriction and thus

Cost–benefit analysis of screening programme for diabetic retinopathy in Bulgaria

British Journal of Clinical Pharmacology, EarlyView.
Aims Late‐diagnosed diabetic retinopathy (DR) is difficult and expensive to treat. Screening programmes can identify the disease early and reduce the costs of its future treatment. This study aims to analyse the cost–benefit of screening programmes for DR.
