UnlabelledAs a consequence of the progress in (perinatal) medicine the number of pregnant women with severe cardiopulmonal risk, who need caesarean delivery, is rising. The anaesthetic care of these patients requires optimal preparation and--as a prerequisite--constant intraoperative vital functions (heart rate, blood pressure, oxygen saturation). Typical risks like airway-problems, hypoxia, hyper- and hypotension and tachycardia must be strictly avoided. We report a case of successful caesarean delivery in a patient with severe coronary heart disease, using spinal catheter technique.Case ReportThe patient was a 36-year-old woman with a symptomatic coronary heart disease. Risk factors were hypercholesterinaemia, obesity (105 kg/168 cm), COPD consecutive to excessive nicotine abuse and hypertonia. Emergency admissions in the 12th and 14th gestation week led to the necessity of PTCA in the 15th and 19th gestation week in spite of pregnancy: coronary stenoses of 90% and 70% were dilated. Caesarean section was scheduled for 38 weeks' gestation, however due to the high risk involved we decided to use a continuous spinal technique. There were no problems with introducing the catheter (28 gauge, L3-4 interspace). Under careful titration a total of 2.2 ml plain bupivacaine 0.5% (spinal catheter) and 0.5 mg alfentanil (intravenously) were administered. This produced anaesthesia up to T8 without any respiratory or cardiovascular embarrassment. A healthy male infant (Apgar score 9/10/10) was delivered. Postoperative analgesia was provided by intrathecal injections of bupivacaine and intravenous injections of piritramide. There were no intraoperative or postoperative problems.DiscussionBy means of continuous spinal anaesthesia for caesarean section it is possible to avoid typical complications of general anaesthesia (hypoxia, airway management, aspiration, tachycardia), of single-shot spinal anaesthesia (hypotension, low or high block) and of epidural anaesthesia (high dose of local anaesthetics, danger of accidental intrathecal or intravenous injection). The possibility of postoperative analgesia is advantageous. Technical difficulties, postspinal headache and the high costs of the sets may be disadvantageous.ConclusionThis case demonstrates, that the use of a continuous spinal catheter technique for caesarean section anaesthesia is an alternative method, which should be considered especially in high risk patients, when meticulous care for constant vital functions is requested urgently.
