What do international guidelines say about therapy?

Purpose: We will discuss the treatment guidelines from the British Hypertension Society, Canadian Medical Association, Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure, the sixth report, and the World Health Organization-International Society of Hypertension. Our emphasis will be on blood pressure thresholds, goals of therapy, non-pharmacologic interventions, choice of first-line agents in uncomplicated patients, individualized therapeutic choices, adjunctive therapy, and future considerations. Data identification: Specific recommendations in international guidelines regarding antihypertensive therapy, that are written in English, easily accessible (i.e., found on the World Wide Web), and current (published in 1997 or later). Conclusions: The reviewed hypertension guidelines strongly favor lifestyle modifications in all patients diagnosed with hypertension, and a trial of lifestyle modification for a specified time period prior to initiating drug therapy is advocated. Pharmacologic therapy should be based on the patient profile: presence of major cardiovascular risk factors, cardiovascular disease, target-organ damage, and concomitant medical conditions, thus allowing for the tailoring of antihypertensive therapy to the individual patient. Thiazide diuretics are the most commonly recommended antihypertensive drug class, based on numerous outcome trials. Finally, new strategies such as low-dose combination therapy are recommended as initial treatment in some patients. J Hypertens 19 (suppl 3): S23-S31 (C) 2001 Lippincott Williams & Wilkins

Factors affecting pain in intravenous catheter placement: Role of depression illness

The aim of the study was to examine factors affecting pain during intravenous (IV) catheter placement in an emergency department. A cross-sectional, observational study was conducted at an academic emergency department. Nine hundred and twenty-five adult patients who had a 20-gauge IV catheter placed were enrolled in the study. Patients were excluded for the following conditions: more than one IV attempt, altered mental status, head trauma, lack of contact due to visual impairment, hearing or speech disorder, intoxication, distracting injury or physical abnormality at the IV site. The magnitude of pain in IV catheter placement was not related to age, sex, experience of the individual placing the IV catheter, site of IV catheter insertion and use of analgesic or antidepressant drugs (p > 0.05). Patients with a history of depression reported significantly higher pain than non-depressed patients (p = 0.001). Depressed patients reported higher severity of pain during IV catheter placement than non-depressed ones. This may influence the decision on whether or not to use local anaesthesia for catheter insertion. © 2005 Blackwell Publishing Ltd
