Electrocardiographic changes during cesarean section: a review

Graded epidural anaesthesia for Caesarean section in a parturient with Shone’s syndrome: a case study

“…Regional anaesthesia has been associated with ischaemic ECG changes in healthy parturients. 12 Our patient did not experience ischaemia; neither symptomatically nor as ECG changes. Compared to mephentermine and ephedrine (both α and β agonists) bolus doses, a phenylephrine (pure α agonist) infusion maintained the BP to the desired level without inducing tachycardia, thus maintaining adequate coronary blood flow in our patient.…”

Anaesthetic Considerations for Patients with Severe Aortic Stenosis

“…The work of the ventricle is increased and thus it requires a greater coronary artery blood flow; as this cannot be achieved the patient may experience angina and suffer subendocardial ischemia. Regional anaesthesia has been associated with ECG changes of ischemia of multifactorial origin in healthy parturients [53]. The detection of transient ischemia requires capture of ECG data from leads II and V5 and an analysis of changes from control.…”

Venous Air Embolism during Surgery, Especially Cesarean Delivery

“…These monitoring systems display the late findings of VAE, detecting the complications of VAE and severe physiologic deterioration caused by V A /Q mismatch, right and/or left heart failure, or paradoxical arterial air embolism (13, 34, 58). Therefore, these methods are not suitable for the early detection of VAE, especially in patients under general anesthesia without N 2 O, and negative findings do not guarantee the absence of VAE.…”

“…The ECG changes during cesarean delivery were known to be nonspecific signs of VAE probably caused by hormonal influence, tachycardia, or patient position (58, 59). However, these monitoring systems are available in the operating room and are familiar to most anesthesiologists.…”
