A prospective autopsy study was undertaken at General Hospital in San Fernando, Trinidad, to analyze deaths that occurred from poisoning during 1996 and 1997. During that period 105 deaths occurred from acute poisoning. The major poisons used were: paraquat (80 cases), organophosphate/carbamate insecticides (10 cases), and anti-psychotic drugs (6 cases). Much less frequently, battery acid, ETHREL[Ethephon; (2-chloroethyl)phosphonic acid], phenols, ethanol, kerosene and flavine were the agents of choice. Suicide accounted for 99 (94.29%) deaths. Of these, 44.44% occurred in the 10-29 y-age-group. Ingestion of paraquat seems almost always fatal, since the large volumes ingested make treatment universally ineffective. Aspiration pneumonitis (100% of cases), and pneumothorax with pneumomediastinum (18.75% of cases), were remarkable autopsy findings in those dying from paraquat poisoning, while asphyxia due to respiratory paralysis was the mode of death from pesticide ingestion. Efforts to prevent suicide by poisoning may be more useful than treatment protocols.

One of the purported benefits to invasive prehospital airway management is the prevention of aspiration; however, aspiration events may occur before the arrival of prehospital personnel. We explore the timing of aspiration in patients with severe traumatic brain injury (TBI) undergoing paramedic rapid sequence intubation (RSI). Severely head-injured (Glasgow Coma Scale [GCS] score 3-8) adults were prospectively enrolled into the San Diego Paramedic RSI Trial. As part of the prehospital data collection tool, paramedics prospectively assessed for clinical evidence of aspiration before RSI (pre-intubation), aspiration events occurring during RSI (peri-RSI), and regurgitation of vomitus or blood after intubation (post-intubation). Data were abstracted from work sheets used during the RSI procedure, a telephone debriefing by one of the principal investigators immediately after delivery of the patient, and San Diego County prehospital and trauma databases. The incidence of pre-intubation aspiration, peri-RSI aspiration, and post-intubation regurgitation of vomitus or blood were determined. Patients with and without pre-intubation aspiration were compared with regard to pre- and post-intubation hypoxia and the rate of aspiration pneumonia. Logistic regression was used to explore the association between pre-intubation aspiration and various demographic and clinical factors. The results showed that pre-intubation aspiration was noted by paramedics in 72/269 patients in whom complete data were available. Peri-RSI aspiration was reported in one patient; there were no reported cases of post-intubation regurgitation of vomitus or blood. Patients in the pre-intubation aspiration group required more intubation attempts, had a higher incidence of desaturations and lower pre- and post-intubation SaO(2) values, and were more frequently diagnosed with aspiration pneumonia. Pre-intubation aspiration was associated with severe TBI, GCS score of 3, younger age, and the absence of alcohol intoxication despite controlling for age, gender, GCS, Head AIS (Abbreviated Injury Score), and serum ethanol. It is concluded that paramedics seem to be able to accurately assess for aspiration in patients undergoing prehospital RSI. The vast majority of aspiration events seem to occur before the arrival of prehospital personnel. Alteration in consciousness from TBI may carry a higher risk of aspiration than with other causes, such as alcohol intoxication.

A 10-yr-old female okapi (Okapia johnstoni) at the San Diego Zoo Safari Park was evaluated for intermittent malaise, inappetence, occasional cough, abdominal splinting, and licking at both flanks. Physical examination revealed tachypnea, tachycardia, and fluid sounds on thoracic auscultation. Transthoracic ultrasound showed multiple uniform, anechoic filled structures in the right and left pleural space. Surgical exploration of the thoracic cavity revealed bilateral, mature, fibrous, compartmentalizing adhesions between the visceral and parietal pleura, confirming a diagnosis of chronic, infectious, fibrinous pleuritis. The suspected etiology was occult aspiration pneumonia secondary to historical episodes of regurgitation associated with general anesthesia. Culture of the pleural fluid and fibrous adhesions grew Trueperella (Arcanobacterium) pyogenes, Arcanobacterium haemolyticum, and few Fusobacterium species. Treatment consisted of chest-tube placement to establish drainage, thoracic lavage, unilateral surgical debridement, and long-term antibiotics. The animal made a complete clinical recovery over 7 mo.
