Handheld Ultrasound (HHUS): Potential for Home Palliative Care

Due to the severity of their disease, palliative care patients often present complex clinical symptoms and complaints like pain, shortness of breath, nausea, loss of appetite, and fatigue. Solely relying on the information available from the history and physical examination often causes uncertainty among palliative care physicians regarding treatment decisions during home visits, potentially leading to unnecessary hospitalizations or transfer to cross-sectional imaging in radiological practices. A rational approach is essential to avoid diagnostic aggressiveness while still providing the imaging information required for optimal palliative care. Bedside use of handheld ultrasound (HHUS) has the potential to expand the diagnostic and therapeutic spectrum in the case of symptom exacerbation but is still underutilized. In this review, we evaluate the potential uses of HHUS in home care settings to provide a more accurate diagnosis of the most common symptoms in palliative patients and to guide bedside interventions such as bladder catheterization, thoracentesis, paracentesis, venous access, and regional anesthesia. Specific training programs for ultrasound in palliative care are currently not available. Adequate documentation is warranted but fraught with technological and privacy issues. Expert supervision and quality assurance are necessary. Despite its limitation and challenges, we suggest that HHUS leads to improved clinical decision-making, expedited symptom relief, and reduced complications without burdening of the patient and costly transfer to hospital or specialty consultations.

The value of ultrasonography in hand surgery

The quality of ultrasound imaging to examine anatomical structures in the wrist and hand has improved highly over the last years. The value of ultrasonography (US) performed by hand surgeons on treatment decisions was investigated in this study. One hundred and ninety-five patients with an unclear clinical hand problem were evaluated by high-definition ultrasonography from January 2005 until June 2007. In 21% of cases, the procedure and therapy were influenced by the ultrasonographic findings. In 26 patients examined by ultrasound, surgery was avoided, while 14 patients had unexpected ultrasound results that led to surgery. In 22 of the 84 performed operations, ultrasound had a direct impact on the surgical procedure itself. The agreement of the ultrasonographic diagnosis and the post-operative diagnosis (n = 80) was better, though not statistically significant compared to the agreement between clinical diagnosis and diagnosis after operation (n = 84). Ultrasound imaging performed by the hand surgeon improves quality in the evaluation of hand problems. Ultrasonography is a cost-effective high-resolution investigation with the possibility of dynamic imaging.

[Therapy of perioperative pain in pediatric urology]

Difficulties in estimating the kind and intensity of pain as well as uncertainty in drug selection and dosing are often responsible for a suboptimal treatment of pain therapy in the various age groups in childhood. The following article will help to minimize these deficits by contributing full details of safe and effective concepts for perioperative pain therapy in childhood.
