Routine determination of morphine, morphine 3-beta-D-glucuronide and morphine 6-beta-D-glucuronide in human serum by liquid chromatography coupled to electrospray mass spectrometry.

A robust liquid chromatographic mass spectrometric method capable of quantifying morphine, morphine 3-beta-D-glucuronide and morphine 6-beta-D-glucuronide down to 1.0 ng/ml, 5.0 ng/ml and 2.0 ng/ml respectively in human serum is presented. The method was validated over linear ranges of 1.0 to 20.0 ng/ml for morphine, 5.0 to 500.0 ng/ml for morphine 3-beta-D-glucuronide and 2.0 to 100.0 ng/ml for morphine 6-beta-D-glucuronide using deuterated morphine as internal standard. In tandem mass spectrometry conditions, the product ions of morphine-3-glucuronide and morphine-6-glucuronide were the ion m/z corresponding to the morphine moiety. By contrast morphine which presented numerous product ions after collision did not allowed a tandem methodology. Compounds were extracted on 100 mg C18 columns and analysed on the PE Sciex API 300 system equipped with a C18 column and electrospray ionisation interface. The interrun precision of quality controls (1.0, 2.0, 10.0, 20.0 ng/ml for morphine, 5.0, 10.0, 250.0, 500.0 ng/ml for morphine 3-beta-D-glucuronide and 2.0, 4.0, 50.0, 100.0 ng/ml for morphine 6-beta-D-glucuronide) was < or =9.3% and accuracy was between 97.9 and 109.8% for each analyte. Sample stabilities in biological matrix were also investigated. This method has been applied to pharmacokinetic analysis of morphine, morphine 3-beta-D-glucuronide and morphine 6-beta-D-glucuronide in human serum.

Parental visitation in the post-anesthesia care unit: a means to lessen anxiety.

Programs that assist parents and children with coping during hospitalization may minimize the emotional trauma of hospitalization and improve both child and family well-being. The purpose of this study was to determine the effect of parental visitation in the Post-Anesthesia Care Unit (PACU) on pre- and postoperative anxiety levels of pediatric patients and parents. Sixty-eight patient-parent pairs were enrolled in the study: 20 before implementing parental visitation and 48 following implementation. Although no differences were found in children's anxiety levels pre- to postoperatively, the anxiety levels of parents who visited their children in the PACU were significantly lower postoperatively.

Using the revised APON standards of practice.

In 1988, the Association of Pediatric Oncology Nurses published its first Scope of Practice Statement. At that time the Standards of Practice were revised in the process outcome format. Six standards refer to direct care of the child and family and a final standard refers to the nurse's professional responsibility to maintain expertise as a specialist or competency as a generalist. The development of these two documents and how they are used by the practitioner and the educator is discussed.

Using and documenting nursing diagnosis in an ambulatory setting.

Documentation and the use of nursing diagnosis have proved to be important in increasing the efficiency of communication and the clarification of nursing services provided. This has led to better utilization of nursing resources. The increased emphasis on ambulatory care has shifted our focus to nurses' roles in clinic and day hospital settings. How do nurses document the care they provide in an ambulatory setting? Can nursing diagnosis be used as effectively in the outpatient department as it has been in the acute or chronic inpatient hospital setting? This article describes how one agency developed a unique documentation tool for ambulatory care which allows for and encourages the use of nursing diagnosis by staff nurses, IV nurses and nurses in expanded roles, and facilitates communication among all nursing personnel.

Unit-based research forums: a model for the clinical nurse specialist to promote clinical research.

Although nurse researchers have generated research findings, practitioners in clinical practice have not consistently utilized them. Evaluation and modification of clinical practice through research is a key component of the role of the clinical nurse specialist (CNS). In this paper, an innovative model is described in which the Clinical Nurse Specialist coordinates specialty-based clinical research through the use of unit-based research forums, an outgrowth of unit-based quality assurance. Such a model allows staff at the unit level to engage in problem-solving dialogues, resulting in increased use of research findings and generation of original research.
