Review Case ReportsRare procedures during delivery room resuscitation--cardioversion of ventricular tachycardia in an asphyctic neonate.
Successful cardioversion of ventricular tachycardia in a full-term male infant, born severely depressed by emergency Cesarean section 9 min after the mother was given bilateral paracervical bupivacaine blocks for pain relief during normal labor, is described. The apparently stillborn baby was resuscitated by conventional means until electronic heart monitoring revealed transition from asystole to rapid ventricular tachycardia 14 min after birth. ⋯ The child recovered rapidly and neurological status at 12 months was normal. Obviously, active search and aggressive management of rapid ventricular arrhythmias are indicated during neonatal resuscitation, if potentially arrhythmogenic drugs are used in perinatal care.

Effect of continuous interscalene brachial plexus block on diaphragm motion and on ventilatory function.
Interscalene block may cause phrenic nerve block and decreased diaphragmatic motion. We evaluated the effect of continuous interscalene block on ventilatory function and diaphragmatic motion. We studied ten patients scheduled for surgery or manipulation of the shoulder. ⋯ In the other five patients, the amplitude of diaphragmatic motility on the side of the block was only 4-37% of the values before the block. All patients had a clear reduction in forced vital capacity (FVC), forced expiratory volume in 1s (FEV1) and peak expiratory flow (PEF) 3 and 8 h after the block without signs of dyspnoea. In conclusion, in all our patients interscalene block caused an ipsilateral hemidiaphragm paresis, which in five of ten patients persisted until the end of the continuous block.

Randomized Controlled Trial Clinical TrialContinuous extrapleural intercostal nerve block and post-thoracotomy pulmonary complications.
To evaluate the effects of continuous extrapleural intercostal nerve block on post-thoracotomy pain and pulmonary complications, a randomized, double-blind, placebo-controlled study was conducted on 80 patients undergoing elective thoracotomy for pulmonary (n = 47) or oesophageal (n = 33) procedures. In patients who received continuous bupivacaine infusion, the requirement for intramuscular opiate and rectal diclofenac was less, the score on a visual linear analogue pain scale lower and recovery of pulmonary function more rapid than in saline-infused controls. ⋯ Among the patients without COAD there was no significant intergroup difference in such complications. We conclude that continuous extrapleural intercostal nerve block is effective for post-thoracotomy analgesia and reduces pulmonary complications of thoracotomy in patients with COAD.
