Police referrals to a psychiatric hospital: experiences of nurses caring for police-referred admissions.

Police are a major source of referral to psychiatric hospitals in industrialized countries with mental health legislation. However, little attention has been paid to nurses' experience of caring for police-referred patients to psychiatric hospitals. This study utilized a Heideggerian phenomenological framework to explore the experiences of nine nurses caring for patients referred by the police, through semistructured interviews. Two major themes emerged from the hermeneutic analyses of interviews conducted with nurse participants: (i) 'expecting "the worst" '; and (ii) 'balancing therapeutic care and forced treatment'. Expecting 'the worst' related to the perceptions nurse participants had about patients referred by the police. This included two sub-themes: (i) 'we are here to care for whoever they bring in'; and (ii) 'but who deserves care?' The second theme balancing therapeutic care and forced treatment included the sub-themes: (i) 'taking control, taking care'; and (ii) 'managing power'. The study raises ethical and skill challenges for nursing including struggling with the notion of who deserves care, and balancing the imperatives of legislation with the need to work within a therapeutic framework.

Risky recreation: synthetic cannabinoids have dangerous effects.

Use of synthetic marijuana (also known as spice, K2, aroma, and eclipse) is often viewed by young people as harmless recreation. Until recently, the substance was freely available in U.S. convenience stores and head shops, and it is still available via the Internet. Emerging evidence shows a wide range of responses to the drug, including paranoia, aggressive behavior, anxiety, and short-term memory deficits. Synthetic cannabinoids are not currently detectable via standard toxicology tests. Recognition and management of synthetic cannabinoid use are discussed.

Bath salts: they are not what you think.

Psychoactive bath salts are a relatively new group of designer drugs sold as tablets, capsules, or powder and pur-chased in places such as tobacco and convenience stores, gas stations, head shops, and the Internet. Bath salts are stimulant agents that mimic cocaine,lysergic acid diethylamide, methamphetamine, or methylenedioxymethamphetamine (ecstasy). The most common bath salts are the cathinone derivatives 3,4-methylenedioxypyrovalerone(MDPV), 4-methylmethcathinone(mephedrone), and 3,4-methylenedioxy-N-methylcathinone (methylone). The drugs cause intense stimulation, eu-phoria, elevated mood, and a pleasurable "rush" Tachycardia, hypertension,peripheral constriction, chest pain, hallucinations, paranoia, erratic behavior,inattention, lack of memory of substance use, and psychosis have been observed in those who have used bath salts. The U.S. Drug Enforcement Administration recently exercised an emergency authority to name three key ingredients in bath salts as Schedule I, thereby making them illegal to possess or sell in the United States. Nursing implications related to both clinical and educational settings are discussed.

Update on marijuana.

Marijuana, the illicit drug most widely used by adolescents, is not a benign substance. Inhalation of marijuana smoke is more harmful than tobacco smoke; cannabis smoke delivers 50% to 70% more carcinogens. Other physiological effects include decreased immune function, higher rates of cardiac arrhythmias, and documented cases of cerebellar infarction. Mood and cognitive effects of marijuana include exacerbation of depression and anxiety (including panic attacks), as well as memory problems that may persist for a month after last use. Cannabis abuse is a risk factor for psychosis in genetically predisposed people and may lead to a worse outcome of schizophrenia. The cumulative respiratory, cardiovascular, metabolic, and mental health risks of marijuana are significant and should be emphasized by nurses who work with adolescents.

Anticholinergic syndrome. Avoiding misdiagnosis.

Anticholinergic syndrome can develop in multiple clinical situations. The disturbance of the central nervous system muscarinic transmission by acetylcholine antagonists or lack of acetylcholine can result in this unpredictable behavioral syndrome. Health care professionals should do the following: Be familiar with common drugs or drug combinations that may induce this condition; Be aware of patients who may be at greatest risk; Be able to identify the cluster of signs and symptoms of anticholinergic toxicity; and Implement appropriate nursing treatment interventions for patients with anticholinergic syndrome. Because this condition is constantly changing, it often is misdiagnosed. Much remains to be studied and understood about the neurophysiology of this condition. Central cholinergic transmission is blocked with the use of many anticholinergic drugs in numerous patient settings. Because acetylcholine plays a significant role in modulating the interactions among most other central transmitters, excessive blockage of this neurotransmitter may result in the unpredictable behavioral condition known as anticholinergic syndrome.

Procainamide-induced psychosis.

The occurrence of procainamide-induced psychosis has not been mentioned previously in the nursing literature and is rarely reported in the medical literature. With the increasing use of procainamide in patients with both atrial and ventricular dysrhythmias, it is quite possible that nurses may encounter the phenomenon more frequently. It is also possible that it has been mistaken previously for ICU or psychologically-induced psychosis. Nurses routinely monitoring patients for physiologic effects of procainamide should also be alert for psychological effects as well. The onset of acute psychological sequelae such as procainamide-induced psychosis further complicates care of physiologically compromised patients. Rapid identification and intervention is important. It is especially important to listen to patient and family cues.
