Vasomotor rhinitis and sphenopalatine ganglion block.

The effectiveness of the sphenopalatine ganglion (SPG) block for the relief of symptoms in chronic vasomotor rhinitis was assessed in 30 patients of both genders. The number of blocks required for complete relief was three (range from two to four) at weekly intervals in 66.7% of volunteers. There was no recurrence of symptoms during a follow-up period of 12-20 months in 29 patients, and one patient was symptom free for 8 months. The technique is simple and can be performed as an outpatient procedure without side effects.

Unilateral celiac plexus block.

Two hundred patients with upper-abdominal malignancy were treated with oral morphine sulfate (OMS) during a 2-year period. Twenty-five of these patients experienced left-sided dragging pain and epigastric discomfort following a few months of adequate pain relief. An increase in the OMS did not relieve the pain. A unilateral left-sided neurolytic celiac plexus block with 20 mL of 50% alcohol was performed using a classical posterior percutaneous approach. This adjuvant technique yielded complete pain relief until death (15-75 days) in 22 patients. All of these patients continued to receive OMS without reduction in dose. Three patients required repeat block after 90 days. This experience documents the value of unilateral celiac plexus block as an adjuvant technique for the management of pain due to upper abdominal cancer.

Operative management problems in nephrobronchial fistula.

During left subcapsular nephrectomy in a patient with nephrobronchial fistula, the purulent material entered the bronchial tree through the fistulous tracts and flooded the dependent right lung. Patchy atelectasis and later massive consolidation of the lower lobe of the right lung ensued ultimately causing her death. A plea is made to use double-lumen endobronchial tubes for anesthesia to prevent such spillover of purulent secretions to the contralateral lung from the kidney. The fistulous tracts should be divided as the first step during surgery, before mobilization of the kidney. In a suspected case, retrograde pyelography should be done preferably under local or regional anesthesia, so that the patient could cough out the contrast material and purulent secretion that might enter the bronchial tree under pressure during the procedure.
