OBJECTIVE: The greater acceptance of acupuncture by healthcare professionals and the public has increased the importance of addressing public concern about its safety. Of particular concern has been the potential for transmission of infectious disease and organ and tissue injury, as well as the training and professional standards of acupuncture practitioners. This paper, therefore, addresses the following question: What is the frequency and severity of adverse complications and events in acupuncture treatment?

BACKGROUND: Low mean arterial pressure (MAP) and deep hypnosis have been associated with complications and mortality. The normal response to high minimum alveolar concentration (MAC) fraction of anesthetics is hypotension and low Bispectral Index (BIS) scores. Low MAP and/or BIS at lower MAC fractions may represent anesthetic sensitivity. The authors sought to characterize the effect of the triple low state (low MAP and low BIS during a low MAC fraction) on duration of hospitalization and 30-day all-cause mortality.

BACKGROUND: The bark of Terminalia arjuna L. (Combretaceae) is used in Ayurveda since ancient times for the treatment of cardiac disorders. Previous laboratory investigations have demonstrated the use of the bark in cardiovascular complications. The present study was aimed to find the effect of 70% alcoholic extract of Terminalia arjuna on anaesthetized dog blood pressure and probable site of action.

100 patients with acute myocardial infarction were given 5 mg of sublingual isosorbide dinitrate within 36 hours by the onset of their symptoms. 86 patients did not show any unusual effect after the administration of the drug; their heart rate was only slightly increased and their arterial pressure slightly reduced. 14 patients developed severe systemic arterial hypotension, associated with absolute or relative bradycardia, within 30 minutes of receiving the drug. All the patients complained of fainting and sweating, 1 patient developed a syncope.

Pericardial tamponade should always be suspected in the clinical setting of any penetrating wound to the thorax or upper abdomen. The most reliable diagnostic criterion is the triad of hypotension, tachycardia and an elevated central venous pressure. Pericardiocentesis should be performed as a temporizing measure until definitive surgical therapy can be carried out. If the patient suddenly decompensates or arrests in the emergency department, immediate thoractomy with evacuation of the pericardial clot and open chest cardiac massage should be performed. Four case reports are presented.

In a 64-year-old male, recurrent syncope, hypotension and bradycardia developed repeatedly. The systolic blood pressure fell and could not be measured by auscultation method and the heart rate decreased to under 20 bpm. He recovered from unconsciousness in several minutes. No precipitating cause was apparent for such episodes. Physical examination revealed swollen lymph nodes in the upper cervical regions. Carotid sinus massage caused a fall of systolic blood pressure by 40 mmHg and the P-P interval lengthened to 1.96 sec. The otolaryngeal examination showed neoplasma in the pharynx.

Two groups of six beagle dogs received rapid intravenous (IV) injections of ropivacaine or bupivacaine on two occasions in a blinded random fashion. Initially, a dose sufficient to cause convulsions (CD) was given followed by twice the CD (2 x CD), which was administered 48 h later. The CD of bupivacaine (4.3 mg/kg) and ropivacaine (4.9 mg/kg) caused significant (P less than 0.05) increases in heart rate and mean arterial blood pressure. There was no difference between drug groups. Seizures were abolished by 10 mg/kg of intravenous thiamylal.

Cyclic antidepressant overdose involves a risk of generalized seizures and cardiovascular disturbances. We have conducted a retrospective study to test the hypothesis of a relationship between generalized seizures and the onset of arrhythmia, hypotension or cardiac arrest during cyclic antidepressant intoxication. Patients who had seizures after ingestion of toxic amounts of tri- or tetracyclic antidepressants were included. Limb-lead QRS complex duration and systolic blood pressure were recorded before and after seizure.
