CSF progesterone and spread of subarachnoid anaesthesia in pregnancy.
Sir,—Hirabayashi and colleagues [1] suggested that a sustained (at least 3–4 months) increase in cerebrospinal fluid (CSF) progesterone concentration may be necessary to produce enhanced spread of spinal anaesthesia in pregnant women. We believe that these conclusions are misleading and unsupported by the results. Maximum cephalad spread of analgesia was quoted as being higher in the second tri...
متن کاملMethod for monitoring plasma progesterone concentrations in pregnancy.
We present a time-series model for monitoring concentrations in plasma of hormones produced in the placenta, progesterone being chosen as an example. The model, which is based on the assumption that variations in plasma progesterone concentration in pregnant subjects mainly reflect variations in the growth rate of the placenta, was applied to eight series of progesterone values measured during ...
متن کاملPlasma concentrations of LH, prolactin, oestradiol and progesterone in female red deer (Cervus elaphus) during pregnancy.
Peripheral blood samples were collected throughout pregnancy from 11 red deer hinds. During the same period, 6 other hinds which mated but failed to produce calves were also sampled. Pretreatment of some of these hinds included synchronization of oestrus alone (N = 3) or with injection of 1000 i.u. PMSG (N = 9). During early and mid-pregnancy, LH and prolactin were frequently undetectable. Prol...
متن کاملValidation of Blubber Progesterone Concentrations for Pregnancy Determination in Three Dolphin Species and a Porpoise
Recent studies have validated the use of biopsies as a minimally invasive way to identify pregnant females in several species of wild cetaceans: Balaenapteraacutorostrata , Delphinusdelphis , Lissodelphisborealis, and Lagenorhynchusobliquidens. These studies found that progesterone (P4) concentrations quantified from blubber attached to biopsy samples is diagnostic of pregnancy. Here we examine...
متن کاملMilk progesterone concentrations: an accurate early pregnancy diagnostic aid in dairy cattle
The optimal day of milk sampling for pregnancy diagnosis by milk progesterone quantitation was determined as well as the diagnostic efficiency of the test for days 14 24 post insemination in dairy cattle. The results show that on days 22 and 23 after insemination diagnostic efficiencies of approximately 100% can be obtained. Enzymeimmunoassay (ELISA) has numerous advantages over the radioimmuno...
