Abstract

BACKGROUND:

In patients with heart failure, many indexes are available for noninvasive identification of pulmonary congestion: E/E' at echocardiography; plasma levels of brain natriuretic peptide (BNP) (pg/ml); number of B-lines at lung ultrasound; and transthoracic conductance [thoracic fluid content (TFC)TT = 1/Ω] at impedance cardiography (ICG).

METHODS:

We obtained 75 measures from 50 patients (72 ± 10 years, NYHA 2.4 ± 0.7, ejection fraction 31 ± 7%), 25 of them studied before and after intravenous diuretics, in whom we assessed the following: E/e' from Doppler echocardiogram; BNP plasma levels; presence and number of B-lines at lung ultrasound; and TFCTT from ICG. We determined the relationship among these indexes and their change with treatment, and compared B-lines and TFC for the diagnosis of pulmonary congestion. Finally, we considered the timing and the personnel required for performing and interpreting each test.

RESULTS:

A mutual relationship was observed between all the variables. After clinical improvement, changes in each variable were of similar direction and magnitude. Congestion (estimated by chest radiograph) was present in 59% of the patients: TFC value and B-line number had the best sensitivity and specificity for its detection. BNP determination and ICG assessment were performed by a nurse (15 min), and echocardiography and lung ultrasound were performed by a cardiologist (15 min).

CONCLUSION:

The correlation between all indexes and their consensual change after improvement of the clinical status suggests that they all detect pulmonary congestion, and that using at least two indexes improves sensitivity and specificity. The choice among the methods may be determined by the patient characteristics or by the clinical setting.

La formazione in telemedicina è equiparabile alla formazione di persona?

Leggendo questo articolo sembrerebbe proprio così anche se sarei curioso di capire la metodica del corso per via telematica e che tipo di tutoraggio è stato messo in opera......

A comparison of telemedicine teaching to in-person teaching for the acquisition of an ultrasound skill - a pilot project.

Abstract

Telemedicine is widely used for medical education but few studies directly investigate how telemedicine teaching compares to conventional in-person teaching. Here we determine whether telemedicine teaching is as effective as in-person teaching for the acquisition of an ultrasound skill important in trauma care. Nurses with no prior ultrasound experience (n = 10) received study material and a teaching session on how to locate and image the hepatorenal space (Morison's pouch). One group of nurses was taught in-person (In-person Group) and the other group was taught via telemedicine (Telemedicine Group). Telemedicine allowed two-way audio and visual communication between the instructor and the nurses. A comparison of the teaching techniques showed that telemedicine teaching was equivalent to in-person teaching for the acquisition of practical and theoretical skills required to locate Morison's pouch. The average time required to locate Morison's pouch after teaching was similar between both groups. The results demonstrate that telemedicine teaching is as effective as in-person teaching for the acquisition of bedside ultrasound skills necessary to identify Morison's pouch. Remote teaching of these bedside ultrasound skills may help in the diagnosis of intra-abdominal bleeding in rural healthcare centers.

Abstract

BACKGROUND:

Ten percent of the time, peripheral intravenous access (PIV) is not obtained in 2 attempts in the emergency department. Typically, a tourniquet is used to dilate the target vein; but recent research showed that a blood pressure (BP) cuff improves dilation, which may translate to increased PIV success.

OBJECTIVES:

We sought to determine if there is improved success in obtaining ultrasound-guided PIV using a BP cuff vs a tourniquet in "difficult stick" patients.

METHODS:

This is a prospective, randomized, single-blinded trial. Adult patients requiring PIV with at least 2 prior failed attempts were enrolled. Patients were assigned to tourniquet or BP cuff for target vein dilation randomly. Nurses prepared the patient for PIV attempt by either placing a BP cuff inflated to 150 mm Hg or placing a tourniquet on the chosen extremity. The extremity was draped to blind the physician to assignment. Physicians then attempted ultrasound-guided PIV. Failures were defined as IVs requiring greater than 3 ultrasound-guided attempts or 30 minutes, or patient intolerance. If failure occurred, the physician was unblinded; and the patient could be crossed over and reattempted.

RESULTS:

Thirty-eight patients were enrolled. The success rate for the tourniquet group (n = 17) and BP cuff group (n = 21) was 82.4% and 47.6%, respectively (P = .04). There were no differences between groups for vessel depth, diameter, or procedure time. Six in the BP cuff group were crossed over and had successful PIV obtained with tourniquet.

CONCLUSIONS:

Tourniquet is superior to BP cuff for target vein dilation in ultrasound-guided PIV.

ASSE LUNGO UGUALE ALL'ASSE CORTO?

Ricerca sul reperimento di accesso vascolare su fantoccio. Sarebbe interessante verificare che tipo di fantoccio fosse perchè se fosse con superficie piana sarebbe uguale la difficoltà nella tecnica d'incannulamento mentre se fosse stato cilindrico,  tecnica in asse corto vs quella in asse lungo, avrebbero difficoltà diverse come sanno i colleghi che impiantano.
Ottimale sarebbe stata una ricerca del genere sul campo con tutte le variabili del caso.

Abstract

INTRODUCTION:

Our primary objective was to describe the time to vessel penetration and difficulty of long-axis and short-axis approaches for ultrasound-guided small vessel penetration in novice sonographers experienced with landmark-based small vessel penetration.

METHODS:

This was a prospective, observational study of experienced certified emergency nurses attempting ultrasound-guided small vessel cannulation on a vascular access phantom. We conducted a standardized training, practice, and experiment session for each participant. Five long-axis and five short-axis approaches were attempted in alternating sequence. The primary outcome was time to vessel penetration. Secondary outcomes were number of skin penetrations and number of catheter redirections. We compared long-axis and short-axis approaches using multivariable regression adjusting for repeated measures, vessel depth, and vessel caliber.

RESULTS:

Each of 10 novice sonographers made 10 attempts for a total of 100 attempts. Median time to vessel penetration in the long-axis and short-axis was 11 (95% confidence interval [CI] 7-12) and 10 (95% CI 6-13) seconds, respectively. Skin penetrations and catheter redirections were equivalent and near optimal between approaches. The median caliber of cannulated vessels in the long-axis and short-axis was 4.6 (95% CI 4.1-5.5) and 5.6 (95% CI 5.1-6.2) millimeters, respectively. Both axes had equal success rates of 100% for all 50 attempts. In multivariable regression analysis, long-axis attempts were 32% (95% CI 11%-48%; p=0.009) faster than short-axis attempts.

CONCLUSION:

Novice sonographers, highly proficient with peripheral IV cannulation, can perform after instruction ultrasound-guided small vessel penetration successfully with similar time to vessel penetration in either the long-axis or short-axis approach on phantom models.

Advances in wound debridement techniques.

Abstract

Dead and devitalised tissue interferes with the process of wound healing. Debridement is a natural process that occurs in all wounds and is crucial to healing; it reduces the bacterial burden in a wound and promotes effective inflammatory responses that encourage the formation of healthy granulation tissue ( Wolcott et al, 2009 ). Wound care should be part of holistic patient care. Recent advances in debridement techniques include: biosurgery, hydrosurgery, mechanical debridement, and ultrasound. Biosurgery and mechanical debridement can be practiced by nonspecialist nurses and can be provided in a patient's home, thus increasing the patient's access to debridement therapy and accelerating wound healing.

Focused simulation training: emergency department nurses' confidence and comfort level in performing ultrasound-guided vascular access.

Abstract

STUDY OBJECTIVES:

The objective of this study is to assess Emergency Department (ED) nurses' confidence, comfort level, and competency in performing ultrasound-guided vascular access after a focused ultrasound simulation training session.

METHODS:

A cross-sectional study at an academic medical center. A simulation-based ultrasound training module was used to train ED nurses in ultrasound-guided intravenous (IV) access. The training module consisted of didactics followed by hands-on practice on human models and Blue Phantom ultrasound training block model. All subjects completed a questionnaire after completing the training module.

RESULTS:

A total of 40 nurses were enrolled. All subjects successfully demonstrated competency during the training session by identifying upper extremity sonographic vascular anatomy on a human model and performing real-time ultrasound-guided IV access on Blue Phantom ultrasound training block model. On a scale of 1-10, the average confidence level in performing the ultrasound-guided vascular access was 6.9 [95% confidence interval (95% CI) 6.3-7.46], with 98% (95% CI, 92-102%) reporting no difficulty in recognizing upper limb vascular anatomy on ultrasound. Ninety-two percent (95% CI, 84-100%) agreed that focused training in ultrasound-guided IV access was adequate to learn the procedure.

CONCLUSIONS:

After a focused simulation training session, ED nurses had a high level of comfort using ultrasound for vascular access. Despite having a moderate degree of confidence, ED nurses were accurate in identifying vascular anatomy and performing ultrasound-guided vascular access.

Sonographer statunitense: qualche indicazione per chi volesse andare oltreoceano

 

http://study.com/articles/Sonogram_Nurse_Job_Description_Duties_and_Requirements.html#relatedSchoolsList

Essential Information

The job title of 'sonogram nurse' is not a typical one. Licensed nurses can gain training in ultrasound and sonography by pursuing an additional certificate or degree program in diagnostic medical sonography; however, holding a nursing degree and licensure is not a prerequisite for these programs. Some prior healthcare experience does tend to be valuable for aspiring sonographers, though. Nurses who complete a diagnostic medical sonography program might continue their nursing practice, or they may transition into a sonographer role.
Healthcare practitioners who perform sonograms use a transducer to transmit high frequency sound (ultrasound) waves into a patient's body. The transducer takes an image of the body part using reflected echoes, and the sonographer sends the image to the physician for diagnosis of disease and pregnancy health. Sonographers can find employment in hospitals, doctor's offices and laboratories.

Required Education Certificate or degree program
Other Requirements Strong communication skills, expertise with sonogram equipment and in-depth knowledge of anatomy and physiology
Certification and Licensure Certification is recommended for sonographers; licensure is required for sonographers in some states
Projected Job Growth (2012-2022)*19% for all registered nurses; 46% for all diagnostic medical sonographe

Requirements for Nurses Who Want to Become Sonographers

There are several paths open to nurses who want to study sonography.The programs available may take anywhere from 1-4 years to complete. All require some background in anatomy and mathematics.
A certificate program is offered by some hospitals and medical institutes. These programs can vary in length from 1-2 years. Most programs include lectures, on-campus experience with sonographic equipment and off-campus clinical studies. Some programs require prior experience in a healthcare facility; a licensed nurse interested in this type of program would easily fulfill this requirement.
An associate's degree program is offered by many university hospitals and community colleges. This is a 2-year program that usually requires a background in anatomy, physics and college level math. The curriculum generally includes lectures and clinical experience.
Finally, a bachelor's degree program is offered by some 4-year universities. These programs have more extensive prerequisites, including courses in anatomy, physiology, physics and math, as well as general education subjects like English and social sciences. Like associate's degree programs, bachelor's degree programs in diagnostic medical sonography combine classroom discussion with hands-on clinical work and practice on ultrasound equipment.

Certification and Licensure

Although certification isn't mandatory for diagnostic medical sonographers, it's strongly recommended; some insurance companies won't pay for procedures unless certified sonographers perform them, so employers prefer to hire professionals with certification. After graduating from an accredited program, new sonographers can earn certification by passing an exam. Some states require that sonographers be licensed. Eligibility requirements for licensure vary by state, but certification is a common requirement.
