The minimum effective concentration (MEC90) of ropivacaine for ultrasound-guided quadratus lumborum block for analgesia after cesarean delivery: a dose finding study [PDF]

BMC Anesthesiology, 2022
Background Quadratus lumborum block was recently proposed as an alternative technique for post-cesarean delivery analgesia. However, there is not a definite optimum concentration of local anesthetics.

The Minimum Effective Concentration (MEC95) of different volumes of ropivacaine for ultrasound-guided caudal epidural block: a dose-finding study [PDF]

BMC Anesthesiology, 2023
Background Caudal epidural block (CEB) may be beneficial in anorectal surgery because its use may extend postoperative analgesia. This dose-finding study aimed to estimate the minimum effective anesthetic concentrations for 95% patients(MEC95) of 20 ml ...

Phenylpiperidine opioid effects on isoflurane minimum alveolar concentration in cats [PDF]

Journal of Veterinary Pharmacology and Therapeutics, 2020
AbstractDifferent structurally related phenylpiperidine opioids exhibit different isoflurane‐sparing effects in cats. Because minimum alveolar concentration (MAC) in cats is affected only by very high plasma concentrations of some phenylpiperidine opioids, we hypothesized these effects are caused by actions on nonopioid receptors.

Minimum Effective Anesthetic Concentration of Hyperbaric Lidocaine for Spinal Anesthesia [PDF]

Survey of Anesthesiology, 1998
Minimum effective anaesthetic concentration (MEAC) of lidocaine for spinal anaesthesia, defined as the concentration at which a spinal anaesthetic agent produces surgical anaesthesia within 20 min of administration in 50% of patients, was determined in a randomised, double-blind study in young patients undergoing knee and ankle surgery.Using the ...
