Point-of-care ultrasound (POCUS) of the optic nerve sheath diameter (ONSD) has been shown to be useful in identifying patients with increased intracranial pressure (ICP). However, the non-standardized technique for this POCUS has hampered its use. We present a standardized image acquisition protocol for use in the acute care setting.

This protocol presents two techniques to isolate the subcellular compartments of murine rod photoreceptors for protein analysis. The first method utilizes live retinae and cellulose filter paper to separate rod outer segments, while the second employs lyophilized retinae and adhesive tape to peel away rod inner and outer segment layers.

This manuscript details an optimized inoculation protocol that uses detached maize leaf sheaths for reproducible cytological, physiological, and molecular studies of maize interactions with fungal plant pathogens. The leaf sheaths facilitate real-time observation of cellular interactions between the living plant and fungus in unfixed tissues.
FAQs
The sheath separates lengthwise after the catheter has reached its intended position. Pulling the handles or wings divides the sheath into removable portions, so the catheter can remain in place while the introducer exits around it. This controlled sequence reduces the need to move the catheter during access-site withdrawal and supports more precise placement.
Positioning places the sheath along the intended access path, while stabilization helps maintain that path as the catheter advances. These steps support procedural control because the sheath must guide the device before it is separated and removed. Maintaining alignment also helps the catheter reach its intended position before the sheath is withdrawn.
A peel-away sheath provides temporary support during device introduction but does not need to remain as a continuous opening after placement. Once the catheter is positioned, the sheath separates lengthwise and is removed. This approach can minimize disruption at the access site compared with requiring a larger continuous passage for withdrawal.
The sheath is positioned to establish the access path, and the catheter or other device is guided through it toward the intended location. After placement is confirmed by the procedural sequence, the sheath is stabilized as needed, then its handles or wings are pulled to separate and remove it without displacing the catheter.
The technique supports percutaneous vascular access and is used with central venous, dialysis, and other specialized catheters. Its value is greatest when the device must remain positioned while the introducer is removed. The sheath provides temporary guidance during insertion, then leaves the catheter in place for the intended clinical use.
A peel-away sheath combines device guidance with controlled removal, helping clinicians maintain catheter position during the final access step. Its temporary design can reduce disruption at the access site and avoid the need for a larger continuous opening. These features improve procedural control during catheter insertion and specialized vascular access.
