The time course of lactacidemia was studied prospectively in 17 patients during fluid resuscitation for an episode of noncardiogenic shock, in 5 patients after grand mal seizures, and in 5 patients after successful CPR for cardiac arrest. The 9 patients in whom shock was reversed with fluid administration demonstrated a regular decrease in lactate concentrations, which exceeded 5% of the initial value during the first 60 min of treatment. In the other patients who expired despite similar therapy, lactacidemia was not significantly affected. During circulatory shock, repeated lactate determinations represent a more reliable prognostic index than an initial value taken alone. Changes in lactate concentration can provide an early and objective evaluation of the patient's response to therapy.

This is a report of a postal questionnaire survey of 1250 general dental practitioners regarding occurrence of medical emergencies and their choice of emergency drugs and equipment. The response rate was 65 per cent and the results showed that about one in seven practitioners had had to resuscitate a patient. The most common medical emergencies were adverse reactions to local anaesthetics, grand mal seizures, angina pectoris and hypoglycaemia (insulin shock). Nearly all respondents (96 per cent) believed that dentists need to be competent in cardiopulmonary resuscitation, just over a half (55 per cent) felt they were competent in CPR on graduation and a similar figure (57 per cent) felt they could perform effective single person CPR for five minutes. Almost two-thirds (64 per cent) had undertaken CPR courses since graduation. Additionally, the most commonly kept emergency drugs were oxygen (63 per cent) and adrenaline (22 per cent), while the most commonly kept emergency equipment was a manual resuscitator (recoil bag-valve-mask type) which was kept by 27 per cent of the practitioners.

A 35-year-old healthy Dutch woman went on a trek (Lang Tang) in Nepal up to an approximate altitude of about 3800 meters. She had no prior history of any medical problems except attacks of generalized epilepsy when she was 19 years old, which had been controlled with antiepileptic medications. She had had no attacks after the age of 20. A CT scan done around that time had apparently been normal. On this trek she had developed diarrhea which had been cured with norfloxacin 400 mg two times per day for 3 days. Two days later, while descending, she developed a grand mal seizure at an altitude of 3300 meters, after which she developed a classic postictal phase but gradually recovered. She developed grand mal seizures again the next day, but when she went to a travel clinic in Kathmandu, she had been seizure free for 72 hours. She also revealed that she had not suffered from acute mountain sickness on the trek. She also had a prior history of gastroenteritis at high altitude which improved significantly with norfloxacin, a quinolone antibiotic. This was corroborated by her party. Upon examination she was fully conscious and oriented to person, place and time. Her pulse was 70 beats per minute and her BP was 110/80 mm of Hg. Her fundi and cranial nerves exam were completely normal. Her abstract thinking, gait, power, tone, reflexes and other facets of her neurologic exam revealed absolutely no abnormalities. Her cardiovascular exam revealed a normal rhythm with no murmurs or bruits. The rest of her exam was also normal. She revealed that she played tennis on a regular basis and was an outdoor person. She had not trekked before in the Himalayas and it was uncertain if she had been to high altitude before. She was on no medications at the time. There was no history of drug abuse. She did not smoke and consumed few alcoholic beverages. She had not consumed any alcohol on the trek. She was advised to get a CT scan (she declined as she was going home to Holland in 2 days) and she was prescribed a loading dose of phenytoin 1 g orally spread over several hours and it was recommended she take 300 mg of phenytoin per day. She was going to see her neurologist in Holland on arrival there. She went to her hotel in Kathmandu while her friends went to fill the prescription of phenytoin. When her friends returned to the hotel she was having another grand mal seizure. Medical help was sought, but she died before the doctor arrived to control her seizures. When the doctor did arrive and carried out CPR for half an hour it was to no avail as she continued to have no pulse or blood pressure.

We report the case of a 13-year-old boy who, while running in a school gymnasium, experienced sudden syncope and seizure. CPR was started immediately, and an automated external defibrillator (AED) was attached, but shock was not induced. He was referred to our hospital for loss of consciousness and intermittent general tonic-clonic seizure. A 12-lead electrocardiogram showed normal sinus rhythm and no ST-T wave abnormalities. Echocardiography showed normal structural heart and normal cardiac function. On the second day of hospitalization, AED electrocardiogram showed complete atrioventricular (AV) block at syncope and seizure. After the patient recovered from this neurological state, we performed the treadmill exercise test, and it did not show ST-T wave abnormalities or AV block, and he did not complain of chest pain. Coronary angiography showed atresia of the left main trunk and the collateral vessel from the right coronary artery connected to the left coronary artery. He was diagnosed with congenital left main coronary artery atresia. We began administration of calcium antagonist and aspirin to prevent a coronary artery spasm and then performed a coronary artery bypass graft (CABG) to prevent sudden cardiac death. After CABG, he has had no syncope episodes at rest or during light exercise. <Learning objective: In pediatric patients, syncope during strenuous exercise should mandate exclusion of cardiac events, especially coronary artery anomalies. Coronary artery anomalies that could cause sudden cardiac death sometimes show no abnormalities at rest or even during exercise stress on 12-lead electrocardiogram. It is very important to suspect cardiogenic syncope during strenuous exercise.>.
