During the last 4 years three so-called spontaneous perforations of the oesophagus were treated, twice by surgical intervention 12 anys after the rupture. Two patients survived. The classical history of retching or vomiting and retrosternal splitting pain is indicative, wht medium, amidotrizoate sodium (Gastrografin), from the oesophagus. Prognosis depends decisively on the time of operation after the rupture. Direct suture of the rupture with plastic coverage of the defect by sewing on of the gastric fundus or by plication of the fundus have proved valuable.

Classic diaphragmatic flutter, a rare disorder associated with dyspnoea, thoracic or abdominal wall pain, and epigastric pulsations, is caused by involuntary contractions of the diaphragm with a frequency of 0.5-8.0 Hz. We have seen three patients with diaphragmatic flutter of higher frequency not associated with respiratory disease. The patients presented with longstanding oesophageal belching, hiccups, and retching, respectively. The diagnosis was established by the presence on electromyography of the diaphragm and scalene and parasternal intercostal muscles of repetitive discharges of 9-15 Hz. Spirographic tracings, especially those of volume or flow vs time, showed similar high-frequency oscillations superimposed on tidal respiratory movements. Treatment with carbamazepine 200-400 mg three times daily led to disappearance or great improvement of flutter and clinical symptoms in all three patients. The phenomenon was not seen in other patients with chronic hiccups or oesophageal belching or in patients without these symptoms who had undergone electromyography or spirography for other reasons. Thus, high-frequency diaphragmatic flutter seems to be a new disease entity. The response to carbamazepine, which suggests that the flutter causes the symptoms, requires further study.

Ondansetron is a highly potent and selective antagonist at 5-HT3 receptors. Its anti-emetic actions were first revealed by its ability to antagonize retching and vomiting induced by chemotherapy and radiotherapy in animals and man. Subsequently, the availability of labelled 5-HT3 receptor ligands allowed identification of 5-HT3 receptors, located at highest densities in the area postrema, nucleus tractus solitarius (NTS), in other areas of the brain, and on afferent terminals of the vagus nerve. Postoperative nausea and vomiting may be caused by various factors: the anaesthetic, associated drugs, the surgical procedure, movement of the patient, sex, weight and pain. These factors mediate their effects via the higher brain circuits, the vestibular nuclei, the chemoreceptor trigger zone in the area postrema, or the upper gastrointestinal tract via the vagus nerve, influencing motor and visceral emetic outputs in the hind-brain. It is hypothesized that ondansetron blocks nausea and vomiting by 5-HT3 receptor antagonism at two specific sites: (i) centrally, in the area postrema/NTS; and (ii) peripherally on vagus nerve terminals. The absence of other pharmacological effects of ondansetron ensures an absence of side-effects.

There have been claims that the postoperative course of patients may be improved by presentation during general anesthesia of therapeutic suggestions which predict a rapid and comfortable postoperative recovery. This study evaluated the effectiveness of such therapeutic suggestions under double-blind and randomized conditions. A tape recording predicting a smooth recovery during a short postoperative stay without pain, nausea, or vomiting was played during anesthesia to about half the patients (N = 109), while the remaining, control patients were played a blank tape instead (N = 100). The patients were primarily undergoing operations on the fallopian tubes, total abdominal hysterectomy, vertical banding gastroplasty, cholecystectomy, and ovarian cystectomy or myomectomy. The anesthesia methods consisted of either isoflurane with 70% nitrous oxide in oxygen to produce end-tidal concentrations of 1.0, 1.3, or 1.5 MAC; or 70% nitrous oxide in oxygen combined with high or low doses of opioids. Assessments of the efficacy of the therapeutic suggestions in the recovery room and throughout the postoperative hospital stay included: the frequency of administration of analgesic and antiemetic drugs; opioid doses; the incidence of fever; nausea, retching, and vomiting; other gastrointestinal and urinary symptoms; ratings of pain; ratings of anxiety; global ratings of the patients' physical and psychological recoveries by the patients and their nurses; and length of postoperative hospital stay. There were no meaningful, significant differences in postoperative recovery of patients receiving therapeutic suggestions and controls. These negative results were not likely to be due to insensitivity of the assessments of recovery, as they showed meaningful interrelations among themselves and numerous differences in recovery following different types of surgery. Widespread utilization of therapeutic suggestions as a routine operating room procedure seems premature in the absence of adequate replication of previously published positive studies.

This randomized, double-blind study evaluated the antiemetic efficacy and the side-effects of promethazine pretreatment (0.5 mg.kg-1 IV + 0.5 mg.kg-1 IM) versus droperidol + placebo pretreatment (droperidol, 0.075 mg.kg-1 IV + physiological saline, 0.02 ml.kg-1 IM). One hundred unpremedicated ASA physical status I children ranging from two to ten years, and undergoing outpatient strabismus surgery were studied. All children received inhalational anaesthesia with halothane, nitrous oxide and oxygen. Neither opioids nor muscle relaxants were used. The incidence of vomiting and/or retching and the incidence of side-effects were determined in the post-anaesthesia recovery room (PARR), in the short-stay surgical unit (SSSU), and after discharge from the hospital (including the journey and the stay at home during the first postoperative day). Promethazine and droperidol were equally effective in reducing the incidence of vomiting before discharge to two and eight per cent respectively. On the contrary, the incidence of vomiting after discharge and overall were significantly less with promethazine (ten and ten per cent) than with droperidol pretreatment (54 and 56 per cent) (P less than 0.0001). Promethazine permitted the time to discharge from the hospital to be reduced to an average of three hours, without increasing the incidence of vomiting postdischarge. Promethazine pretreatment is much less expensive than droperidol pretreatment. The incidence of restlessness was significantly less with droperidol (eight per cent) than with promethazine (36 per cent) (P less than 0.001). Promethazine pretreatment demands the use of an analgesic like acetaminophen in order to reduce the incidence of postoperative pain and restlessness.(ABSTRACT TRUNCATED AT 250 WORDS)

The hypothesis that the lipid emulsion of the emulsion formulation of propofol is responsible for the low frequency of nausea, retching, and vomiting after propofol anesthesia was tested. A randomized, prospective, and comparative study was performed to evaluate the antiemetic effect of 10% lipid solution in 60 women, ASA physical status I and II, scheduled for ambulatory laparoscopic procedures. Two groups of patients were studied. Induction of anesthesia (thiopental) and maintenance of anesthesia (enflurane, nitrous oxide) were similar in both groups. At induction the study group received 10% Intralipid (3 mL/min for 20 min). The control group received 5% dextrose in lactated Ringer's solution at the same rate. Other drugs administered during or after anesthesia were similar among the groups. The groups were similar with respect to duration of anesthesia, characteristics of early and intermediate recovery, as well as pain scores in the postanesthesia care unit. There were no differences in the amount of antiemetic medications administered or postoperative nausea, retching, or vomiting when the patients were evaluated objectively by a blinded observer or subjectively by patient self-evaluation. It is concluded that 10% Intralipid, the lipid in the emulsion formulation of propofol, does not possess significant antiemetic effects.

Five patients, aged 9-16, living in a community-based home for the mentally retarded, have undergone Nissen fundoplication for gastroesophageal reflux. They were all severely physically handicapped by cerebral palsy. Their symptoms had persisted from 1-10 years, and included chronic retching and vomiting, intermittent obstruction of the upper airways, frequent bronchial and pulmonary infections, and episodic abdominal pain and failure to thrive. Three had hematemesis. Two patients lost a great deal of weight. One had chronic reflux associated with lower airway obstruction, which improved postoperatively. All patients had undergone conservative medical treatment of four to 12 months duration, with no lasting improvement. There were very few postoperative complications. One patient had to be reoperated. After surgical treatment their main symptoms had disappeared and their subsequent management was easier. We have reasons to believe that this condition is seriously underdiagnosed in our society, thereby causing unnecessary pain and distress in patients who are unable to convey their complaints to others.

The authors evaluated the antiemetic properties of transdermal scopolamine (TDS) in healthy patients undergoing elective cesarean section and receiving epidural morphine for postoperative analgesia. Prior to administration of anesthesia, 203 patients had either TDS or a placebo study patch applied behind one ear. All patients were hydrated with lactated Ringer's solution iv and given 2.0% lidocaine with 1:200,000 epinephrine epidurally for surgical anesthesia. Following delivery of the infant, 4 mg of morphine sulphate was injected through the epidural catheter. After the operation patients were evaluated by "blinded" observers at 2, 4, 6, 8, 10, 24, and 48 h for nausea, vomiting, retching, pain relief, itching, and adverse effects. In addition, medications received were noted. No differences were found between the groups in terms of severity or incidence of pain, or requests for analgesic or antipruritic medication. Although there was no difference between the groups in the first 2 h, patients with TDS had significantly less nausea, vomiting, and retching than patients in the placebo group in each time interval between 2 and 10 h. Additionally, the TDS group required less antiemetic medication. There was no difference in the frequency of retching or vomiting between groups. Side effects were minimal and equal in both groups. The authors conclude that TDS results in a decreased incidence of nausea and vomiting in patients who have delivered by cesarean section and received epidural morphine. TDS appears safe for continuous antiemetic administration.

Among the different types of esophageal wall injuries Boerhaave's syndrome is associated with the highest morbidity and mortality. The classical history of retching or vomiting and retrosternal splitting pain is indicative. Roentgenograms of the chest and esophagogram with a water soluble contrast medium are able to reveal the perforation in most cases. Esophagoscopy has been recommended for diagnosis, but its use is unnecessary and frequently contraindicated. Spontaneous perforation of the esophagus should be treated by prompt surgical intervention: left side thoracotomy, direct closure of the perforation by monolayer suture, and adequate mediastinal and pleural drainage. The treatment of esophageal perforation after late diagnosis is considerably more complicated and may consist in a drainage only.

Over a four year period, from August 1987 to July 1991, thirteen cases of chronic and recurrent gastric volvulus were encountered comprising six paediatric and seven adult patients. In none of the patients was the condition clinically suspected; diagnosis being made only at meticulous upper gastro-intestinal (UGI) barium series. The paediatric patients typically presented with obstructive symptoms of projectile vomiting especially after meals and failure to thrive. The adults had variable symptoms of dyspepsia, recurrent intermittent upper abdominal discomfort or pain, occasionally accompanied by vomiting or retching mimicking many different upper abdominal conditions, such as peptic ulcer, biliary tract or pancreatic disease but with negative findings at endoscopy and abdominal ultrasound scanning. All cases were organo-axial type of gastric volvulus. Associated conditions were small sliding hiatus hernia in two adult cases; partial small bowel malrotation in two cases, high jejunal obstruction also in two cases and congenital hip dislocation in one patient. An infant had umbilical hernia, previous meconium cyst and meconium peritonitis. The condition seems not as uncommon as previously thought; the key to diagnosis being constant awareness, a high index of clinical suspicion and a carefully performed UGI barium series especially during the attack of pain.
