*The Trendelenburg position can be used to treat a venous air embolism by placing the right ventricular outflow tract inferior to the right ventricular cavity, causing the air to migrate superiorly into a position within the right ventricle from which air is less likely to embolise.<ref>{{cite journal |vauthors=Orebaugh SL |title=Venous air embolism: clinical and experimental considerations |journal=Crit Care Med |volume=20 |issue=8 |pages=1169–77 |year=1992 |pmid=1643897 |doi=10.1097/00003246-199208000-00017|s2cid=24233684 |url=https://zenodo.org/record/1234786 }}</ref>

Most recently, the reverse Trendelenburg position has been used in minimally invasive glaucoma surgery, also known as MIGS. This position is commonly used for a superior sitting surgeon that uses a combination of downward patient tilt, of approximately 30 to 35 degrees, microscope tilt towards themselves at the same angle and an intraoperative [[gonioscopy|goniolens]] or prisms that allows them to visualise the inferior trabecular meshwork. Some joysticking of the globe may be required with an appropriate goniolens to bring the meshwork into view.{{Citation needed|date=November 2017}}
* The Trendelenburg position along with the [[Valsalva maneuver]], termed as modified-Valsalva maneuver, can also be used for the [[cardioversion]] of [[supraventricular tachycardia]].<ref>{{cite journal|title=Postural modification to the standard Valsalva manoeuvre for emergency treatment of supraventricular tachycardias (REVERT): a randomised controlled trial|journal=Lancet|volume=386|issue=10005|pages=1747–53|doi=10.1016/S0140-6736(15)61485-4|pmid=26314489|year=2015|last1=Appelboam|first1=A|last2=Reuben|first2=A|last3=Mann|first3=C|last4=Gagg|first4=J|last5=Ewings|first5=P|last6=Barton|first6=A|last7=Lobban|first7=T|last8=Dayer|first8=M|last9=Vickery|first9=J|last10=Benger|first10=J|doi-access=free|hdl=11287/593988|hdl-access=free}}</ref>

* The Trendelenburg position is also used when placing a [[central venous catheter]] in the [[internal jugular vein|internal jugular]] or [[subclavian vein]]. The Trendelenburg position uses gravity to assist in the filling and distension of the upper central veins, as well as the external jugular vein. It plays no role in the placement of a femoral central venous catheter.<ref name="Amesur">{{EMedicine|article|422189|Central Venous Access Imaging}}</ref>

*The Trendelenburg position has occasionally been used to produce symptomatic relief from septum posticum cysts of the subarachnoid space in the spinal cord, but does not bring about any long-term benefits.<ref>{{cite journal |vauthors=Teng P, Rudner N |title=Multiple arachnoid diverticula |journal=Archives of Neurology |volume=2 |issue= 3|pages=348–56 |year=1960 |pmid=13837415 |doi=10.1001/archneur.1960.03840090112015 }}</ref>

*If a patient in a [[Fowler's position]] or semi-Fowlers position has sunk too far down into the bed, they may temporarily be put in a Trendelenburg position while staff reposition them.
