Use of sensory descriptors in assessing chronic pain patients.

The present study examined the use of sensory descriptors in assessing chronic pain patients in a multidisciplinary treatment center. Three hundred and eighty-eight chronic pain patients were divided into two groups based on the number of pain sensations which they chose to depict their pain. The results indicated that patients who used numerous sensory descriptors experienced more physical interference and emotional distress and were at greater risk for treatment failure than those patients who used only one descriptor. The results support the utility of sensory descriptors in assessing chronic pain patients.

Hazards in operative management of patients with systemic mastocytosis.

During the past two years, six patients with systemic mastocytosis have required general or regional anesthesia for operative correction of various surgical problems. Mastocytosis constitutes an extremely difficult problem in diagnosis and management. A large experience with patients with mastocytosis in the Vanderbilt Medical Center in the last decade has enhanced awareness of this disorder and increased its early recognition. The hazardous problems of systemic mastocytosis and the difficulties of its diagnosis and management are summarized and focussed on the increased hazard of those patients with this disease who require various surgical operations. Close collaboration between anesthesiologists, surgeons, and internists in this medical center in the past two years has made it possible to carry six of these patients through anesthesia, operation, and the postoperative period safely and without fatality.

Renal transplant arterial stenosis: percutaneous transluminal angioplasty.

Seven hypertensive patients underwent percutaneous transluminal angioplasty for relief of arterial stenosis complicating renal allotransplantation. Five had end-to-side anastomosis of the donor renal artery to the recipient external iliac artery, and two had end-to-end anastomosis of the donor renal artery to the recipient internal iliac artery. Each patient had developed hypertension (blood pressure greater than 145/95 mm Hg), elevated peripheral venous plasma renin, and six demonstrated decrease in renal function as detected by an increase in serum creatinine at least 2 months after transplantation and without evidence of rejection. Angioplasty was technically successful without significant complications and blood pressure and biochemical abnormalities were improved or stabilized in all seven patients.

Localization of gelfoam emboli after partial splenic embolization utilizing 99mTc-labeled emboli.

Partial splenic embolization using 99mTc-labeled Gelfoam was employed to manage of four renal transplant patients with thrombocytopenia and leukopenia. In each patient the individual Gelfoam particles could be seen on the persistence scope of a gamma camera as they arrived in the spleen. This allowed the precise location of each Gelfoam particle to be defined immediately. Gamma camera imaging of the 99mTc Gelfoam particles in the spleen proved as accurate as selective splenic arteriography in determining the amount of spleen embolized. No ectopic 99mTc Gelfoam particles were found as judged by total body gamma camera imaging obtained immediately after the partial splenic embolization procedure was completed.

Partial splenic embolization for hypersplenism in renal transplantation.

Immunosuppressive therapy is necessary in the treatment and prevention of rejection in renal transplant recipients. Unfortunately, these patients may become intolerant to this therapy when it is complicated by hypersplenism with leukopenia and/or thrombocytopenia. The therapy must then be either decreased or stopped, thus preventing adequate treatment or prevention or rejection. Splenectomy has been used to treat the hypersplenism to break this cycle. It requires operative intervention with general anesthesia and prolonged hospitalization, and has been associated with fulminant bacterial septicemia. For these reasons, partial splenic embolization was offered to our patients as an alternative to splenectomy in the treatment of their immunosuppressive therapy intolerance due to hypersplenism. Six patients with acute rejection episodes and one patient on dialysis awaiting transplantation underwent partial splenic embolization. It corrected the hypersplenism in each case without significant complications allowing control of the rejection episode with adequate immunosuppressive therapy in six patients. Strict aseptic technique, pain control, and antibiotic prophylaxis are advised to prevent the complications of splenic abscess, rupture, or septicemia when this technique is used.

The effect of intentional hemodilution on P50.

Ten patients (Group I) scheduled for major vascular surgery received banked blood and twelve patients (Group II) also scheduled for major vascular surgery were administered intentional hemodilution with autologous blood. Both groups of patients were studied to determine the effects of banked blood and autologous blood respectively on P50. The mean pre-operative P50 for Group I and Group II patients were 26.2 mmHg and 26.3 mmHg respectively. The mean postoperative P50 for Group I and Group II patients were 24.7 mmHg and 28.4 mmHg respectively. There was a significant increase in P50 in patients (Group II) who received autologous blood when compared with Group I patients who received banked blood (p less than 0.001). Our data on P50 in Group I patients who received banked blood showed that there was a significant decrease confirming the results of previously published studies. The Authors conclude that intentional hemodilution is an efficacious alternative technique to banked blood administration for patients undergoing major vascular surgery.

Anxiety and postoperative recovery in ambulatory surgery patients.

There has been a growing trend toward one-day ambulatory surgery. Unfortunately, there has been little research evaluating how patients recover at home after one-day surgery. This study examined the relationship between preoperative anxiety and postoperative recovery in ambulatory surgery patients. Fifty women who were scheduled for a laparascopy completed a series of questionnaires on the day before surgery and on each of three days after surgery. One month after surgery, the patients were telephoned and reported on their recovery. The surgeon rated each patient on their estimated degree of anxiety and length of recovery. The results showed that preoperative anxiety partially predicted the patients' psychological and physiological reaction to surgery. Identification of those patients who show high anxiety and distress may help to prevent postoperative complications. These patients may benefit from patient education and psychological interventions to decrease their fears and anxiety and they may benefit from more intensive observation periods following their surgery.

Typical and atypical presentation of malignant hyperpyrexia in nonwhite patients.

Two cases are presented of malignant hyperthermia in black patients. One patient developed signs of malignant hyperthermia during general anesthesia that was successfully treated with dantrolene sodium and cooling. A second patient was retrospectively diagnosed as having an atypical variant of malignant hyperthermia secondary to heat stroke and general anesthesia; this patient subsequently died. These cases illustrate that malignant hyperthermia can occur in blacks despite the very low incidence of this syndrome in nonwhite patients.
