Phrenic nerve palsy (PNP) is seen in infants and young children usually resulting from operative trauma or birth injury. Spontaneous recovery usually occurs, but occasionally surgical plication is necessary. Twenty-three cases of PNP over a 10-year period were managed surgically. Patient ages ranged from 1 day to 30 months (median, 4 months), 18 were male and five female. Cause was operative trauma in 18 (17 cardiac surgery, one neuroblastoma), birth trauma in two, and idiopathic in three. The right side was involved in 14, the left in eight, and both in one. Indications for plication were inability to wean from the ventilator (group 1, 16 patients), recurrent pneumonia (group 2, four patients), and respiratory distress (group 3, three patients). The 16 patients in group 1 were intubated for a median of 18.5 days from onset of PNP to plication. Postoperatively, three had continuing congestive heart failure (one died at 16 days of age, one was still chronically ventilated at 22 months, one was extubated at nine days); the other 13 were extubated at a median of two days postoperatively. All the patients in groups 2 and 3 were extubated within two days of surgery. Twelve plications were transthoracic and 11 were transabdominal. Postoperative complications included pneumonia (2), wound infection (1), pneumothorax (2), and mucous plug with pulmonary collapse (1). One patient died of cardiac failure at 16 days. One patient in group 3 developed recurrent respiratory distress 4 months postoperatively; he had a recurrent elevated hemidiaphragm requiring a second plication.(ABSTRACT TRUNCATED AT 250 WORDS)

A cohort of 24 children with expansile pneumonia caused by Mycobacterium tuberculosis is described in mostly HIV-noninfected children (n = 22). The children presented with nonresolving pneumonia and a swinging fever (83%). On chest radiography, they had dense opacification with bulging fissures mainly in the upper lobes (75%). On computed tomography, the lobes are consolidated, with areas of liquefacation. Other features visible are enlarged mediastinal lymph adenopathy with ring enhancement (100%), cavities (63%), and tracheal compression (71%). On bronchoscopy, bronchi were obstructed by more than 75% in 20 (83%) of cases. Lymph gland enucleation was required in 42% of cases. Phrenic nerve palsy was present in 3 children, of whom 2 underwent diaphragmatic plication. The children received standard antituberculous therapy, to which prednisone (2 mg/kg/day) was added for 1 month. The mortality was 4% after 6 months of therapy.

Phrenic nerve palsy has previously been associated with brachial plexus root avulsion; severe unilateral phrenic nerve injury is not uncommonly associated with brachial plexus injury. Brachial plexus injuries can be traumatic (gunshot wounds, lacerations, stretch/contusion and avulsion injuries) or non-traumatic in aetiology (supraclavicular brachial plexus nerve block, subclavian vein catheterisation, cardiac surgeries, or obstetric complications such as birth palsy). Despite the known association, the incidence and morbidity of a phrenic nerve injury and hemidiaphragmatic paralysis associated with traumatic brachial plexus stretch injuries remains ill-defined. The incidence of an associated phrenic nerve injury with brachial plexus trauma ranges from 10% to 20%; however, because unilateral diaphragmatic paralysis often presents without symptoms at rest, a high number of phrenic nerve injuries are likely to be overlooked in the setting of brachial plexus injury. A case report is presented of a unilateral phrenic nerve injury associated with brachial plexus stretch injury presenting with a recalcitrant left lower lobe pneumonia.

An 83-year-old woman was scheduled for surgery of the left upper and lower extremity fracture. She had past history of lung partial resection for lung cancer and rheumatoid arthritis, and recent history of pneumonia. She also had fluid retention in the thoracic cavity. Open resection of the femoral neck fracture was first performed uneventfully under spinal anesthesia with bupivacaine 0.5% 2 ml. Then, interscalene blaxioplexus block was performed with 0.75% ropivacaine 15 ml and 1% lidocaine 10 ml for tension band wiring of the fractured olecranon. Midazolam 1 mg and propofol 1.5 mg x kg(-1) x hr(-1) were administered for sedation. Thirty minutes after the block, oxgen saturation decreased to 92% under O2 3 l x min(-1) by a mask. She was intubated and arterial carbon dioxide tension was above 150 mmHg. A few hours later, she became conscious and mask CPAP was used after extubation for one day. Pa(CO2) was 90-100 mmHg for 3 days and decreased to 56.9 mmHg on the 6th day, but her consciousness had been clear. Phrenic nerve palsy and sedation in the patient with decreased lung function might have induced prolonged hypercapnea.
