Inactivation of prefrontal cortex attenuates behavioral arousal induced by bilateral electrical stimulation of basal forebrain in sevoflurane-anesthetized rat.

Creator: Chris W. Fields & Jon G. Dean

Duration: 6:30

The video in left panel shows behavioral arousal after bilateral electrical stimulation of basal forebrain (200 Hz, 30 s ON, 30 s OFF, 60 – 100 µA) in a female Sprague Dawley rat (session 1). Note that the behavioral arousal after electrical stimulation occurred under continuous sevoflurane exposure; the rat was breathing 1.7% sevoflurane before, during, and after recovery of the righting reflex. The right panel shows the effect of bilateral electrical stimulation in the same rat (session 2;~1 week later) after inactivation of prefrontal cortex with bilateral infusion of 156 µM tetrodotoxin. The inactivation of prefrontal cortex attenuated the arousal-promoting effects of basal forebrain stimulation. The traces on top of the video show the electroencephalographic activation induced by electrical stimulation. The lightning bolt in the upper right-hand corner indicates when the electrical stimuli were being delivered.

SAP block can be performed in supine or lateral position. Using a 12-15 MHz linear ultrasound probe, scanning starts from the midclavicular line just below the clavicle. The ribs are counted with caudal and lateral probe movement until the 4th and 5th ribs are identified in the midaxillary line. The in-plane needle approach and injection is usually performed in an anteroposterior or craniocaudal direction in the midaxillary line at the level of the 4-5th ribs with LA deposition above (superficial SAP) or below (deep SAP) the serratus anterior muscle

The PIF block is performed under ultrasound guidance, with either cranio-caudal or latero-medial needle advancement. The latter has been proposed to avoid inadvertent puncture of the perforating branch of the internal thoracic artery or the anterior perforating veins joining the internal thoracic vein, with the goal to deposit LA between the pectoralis major and intercostal muscles. The craniocaudal in-plane needle approach and injection is usually performed 1 cm lateral to the sternum at the midsternal level with LA deposition between the pectoralis major and intercostal muscles.

PECS I&II blocks

Creator: Marta Kelava

Duration: 1:16

A 12-15 MHz linear ultrasound probe is placed at a midclavicular line below the clavicle. The probe is moved inferolaterally to the level of the 3rd rib. With a slight medial tilt, the three layers of muscles are identified: pectoralis major, pectoralis minor and serratus anterior. When performing both blocks simultaneously, single puncture site can be used to preserve near-field imaging with deposition of the LA between the layers of the serratus anterior and pectoralis minor (PECS II), followed by needle withdrawal and injection between the pectoralis minor and pectoralis major (PECS I)

The ESP block is performed in a sitting, prone or lateral decubitus position under ultrasound guidance. A high frequency (12-15 MHz) linear array transducer is placed in a parasagittal plane and moved from a lateral to medial direction until the ribs are no longer visualized and transverse processes of T3-5 are identified. An in-plane needle is inserted in the craniocaudal direction and advanced below the erector spine muscle with the tip contacting the T5 transverse process. LA is injected and lifting of the erector spine muscle off the transverse process with craniocaudal spread of the LA is confirmed.

The ME four chamber view is analyzed using the Automated Function Imaging (AFI) software package. The LV long axis strain model is applied to the RV to allow correct labeling of septal segments. Tracking quality is automatically assessed for each segment (green: good or red: poor). Parametric display provides measurements for each of the six RV and global strain. The latter is normal at – 22.3% with regional peak variability with basal segments below normal limits. RV myocardial region of interest is redefined and the septum de-selected to obtain RV free wall strain that is measured at approximately -22%

Then, the probe is moved caudally following the internal jugular vein in the center of the monitor. Once the probe has reached the clavicle, it is inclined following the internal jugular vein to identify where it merges with the right subclavian vein and the underlying pleura on the long-axis view. The puncture needle is inserted using the long-axis view and advanced while identifying the needle point in real-time, until it reaches the right brachiocephalic vein.

How to Perform Focused Cardiovascular Ultrasound

Creator: Dr. Josh Zimmerman, MD, FASE

Duration: 23:23

A brief, screen-in-screen review of the techniques required to perform bedside cardiac ultrasound at the parasternal, apical, and subcostal windows.

Play

Video 1: Normal parasternal long axis

Creator: Dr. Josh Zimmerman, MD, FASE

Duration: 0:08

The right ventricle is under the transducer. There is normal excursion and coaptation of the aortic and mitral valves. The chambers are normal in size. There is brisk excursion of the aortic root, brisk opening of the mitral valve, a normal descent of the base of the MV, and normal thickening of the left ventricular segments.

Play

Video 2: Significant aortic stenosis seen in the PLAX

Creator: Dr. Josh Zimmerman, MD, FASE

Duration: 0:06

The aortic valve is heavily calcified and does not open well. The degree of stenosis cannot be quantified from this view, but with excursion this limited the assumption should be that the patient has severe stenosis until it is proven otherwise. In addition to aortic valve calcification, the mitral annulus is heavily calcified, there is left ventricular hypertrophy, and the left atrium is enlarged.

Video 4: Dilated cardiomyopathy seen in the PLAX

Creator: Dr. Josh Zimmerman, MD, FASE

Duration: 0:08

The RVOT, LA, and LV are all dilated and appear proportionally large compared to the aortic annulus and root. Compare the relative sizes with Video 1 (normal PLAX.) There is evidence of decreased LV systolic function, with decreased motion of the aortic root, decreased excursion of the anterior mitral leaflet, decreased mitral annular excursion, and decreased thickening of the left ventricular segments. There is also a left pleural effusion.

Play

Video 5: Rheumatic mitral disease seen in the PLAX

Creator: Dr. Josh Zimmerman, MD, FASE

Duration: 0:05

Left ventricular and aortic valve function appear normal. There is thickening of the tips of the mitral leaflets, with diastolic bowing seen particularly in the anterior mitral leaflet (the “hockey stick” appearance). The left atrium appears enlarged as well, consistent with elevated left atrial pressure from mitral stenosis.

Play

Video 6: Systolic anterior motion of the anterior mitral leaflet in the PLAX

Creator: Dr. Josh Zimmerman, MD, FASE

Duration: 0:07

Multiple beats are shown in this clip and the image does not remain still because the patient was severely dyspneic. The patient has significant hypertrophy of the anterioseptal wall of the left ventricle. In multiple cardiac cycles the anterior mitral leaflet can be seen to impinge on the left ventricular outflow tract.

Play

Video 7: Both pleural and pericardial effusions seen in the PLAX

Creator: Dr. Josh Zimmerman, MD, FASE

Duration: 0:05

The descending thoracic aorta is outside the pericardium, and a pericardial effusion will be seen extending between the heart and the aorta in this view while a pleural effusion will be seen deep and lateral to the aorta.

Video 8: Normal parasternal short axis (PSAX.)

Creator: Dr. Josh Zimmerman, MD, FASE

Duration: 0:07

The right ventricle is seen to the left of the screen, with the anterior portion of the left ventricle closest to the probe. The papillary muscles are seen, identifying this as the mid-portion of the left ventricle. Six segments of the left ventricle are seen, representing all three main coronary artery territories.

Creator: Dr. Josh Zimmerman, MD, FASE

Duration: 0:08

The interventricular septum (IVS) is normally convex with respect to the left left ventricle throughout the cardiac cycle. In this case the IVS is flat in both systole and diastole, suggesting that the right and left ventricular pressures are similar (near systemic pulmonary artery pressures.)
