Unnecessary emergency caesarean section due to silent CTG during anaesthesia?

We present a case of a probably unnecessary Caesarean section due to misinterpretation of the cardiotocography (CTG) trace during general anaesthesia. A 27-yr-old patient in her 30th week of an uneventful, normal first pregnancy presented with a deep venous thrombosis in the pelvic region. She was to undergo an emergency thrombectomy under general anaesthesia. During the operation, the CTG showed a lack of beat-to-beat heart rate variation (silent pattern CTG) with normal fetal heart rate. This silent CTG pattern was probably a result of the effect of general anaesthesia on the fetus. The CTG pattern was interpreted as indicating fetal distress, and an emergency Caesarean section was performed after the thrombectomy. The infant was apnoeic and had to be resuscitated and admitted to the neonatal intensive care unit. The pH at delivery was 7.23 and the baby was extubated 2 days later. Mother and child recovered without short-term sequelae. In the absence of alternative explanations, reduced fetal beat-to-beat variability with a normal baseline heart rate during general anaesthesia is probably normal.

Cefaclor af versus amoxycillin/clavulanate in acute bacterial exacerbations of chronic bronchitis: a randomised multicentre study.

Cefaclor and amoxycillin/clavulanate are active against Haemophilus influenzae, Streptococcus pneumoniae, Moraxella catarrhalis and Staphylococcus aureus--pathogens commonly associated with acute exacerbations of chronic bronchitis (AECB). This randomised, parallel-group, single-blind, multicentre study investigated the comparative efficacy and safety of 7-day treatment regimens of cefaclor AF (750 mg b.d. [n = 73]) and amoxycillin/clavulanate (875/125 mg b.d. [n = 72]) in AECB. A favourable clinical response was obtained in 95.9% of patients on cefaclor AF and 97.2% of patients on amoxycillin/clavulanate. There were no statistically significant differences between the groups for improvement in clinical response measured by pulmonary peak expiratory flow (PPEF), or for common symptoms associated with AECB. Both agents were well tolerated, with no statistically significant differences in overall safety; however, nausea and vomiting, and abdominal pain, the most frequently occurring adverse events in the amoxycillin/clavulanate group, were not reported in the cefaclor group. In conclusion, cefaclor AF and amoxycillin/clavulanate have similar efficacy and safety profiles in the treatment of AECB.
