Introduction - The exact pathogenesis of canine peripartal uterine inertia has been studied in little detail. Changes in the concentration of serum ionised calcium (iCa), parathyroid hormone (PTH) and venous pH were examined during the peripartal period in the bitch. We postulated that an acute respiratory alkalosis may be associated with the onset of whelping which would reduce the amount, and delay the secretion of, PTH in response to increased calcium demand (3). Subsequent subclinical hypocalcaemia would lead to uterine inertia with delayed delivery and intrapartal hypoxia of puppies (1).
Materials and methods - Bitches were selected from a colony of German Shepherds with a history of uncomplicated parturition (Group 1: Control; n=10) and from a Labrador colony experiencing an increased incidence of stillbirths (Group 2; n=20). Jugular blood samples were collected daily from –96 h until the onset of whelping (Time 0 = onset of stage 2 labour) and then every 4 h until the last pup was born. Serum was processed and stored under anaerobic conditions until analysis by radio-immunoassay (PTH; 4), ion selective potentiometry (iCa; 5) and an i-Stat portable analyser (pH). Multiple linear regression was used to determine the effect of the independent variables (group and time) and their interactions on each of the dependent variables (PTH, iCa, and pH).
Results - Mean concentrations of serum PTH, iCa and pH during the peripartal period in Group 1 bitches are tabulated below: [...]
