A method and solution for perioperatively inhibiting a variety of pain and inflammation processes during arthroscopic procedures. The solution preferably includes a vasoconstrictor that exhibits alpha-adrenergic activity and one or more additional pain and inflammation inhibitory agents at dilute concentration in a physiologic carrier, such as saline or lactated Ringer's solution. The solution is applied by continuous irrigation of a wound during a surgical procedure for peripheral vasoconstriction and inhibition of pain and / or inflammation while avoiding undesirable side effects associated with systemic application of larger doses of the agents.

Systems and methods provide for automated, cyclic delivery and evacuation of a treatment or irrigation solution from a tooth root pulp chamber and pulp canals. A manifold has a base member sized and configured to rest on a crown of an instrumented tooth and a top member sized and configured to couple with the base member to define an inlet chamber and an outlet chamber. The distal end of a needle is passed through an opening between the inlet and outlet chambers and extended distally beyond the base member into a pulp canal. The proximal end of the needle includes an opening in fluid communication with the inlet chamber. A solution is transferred from a fluid supply source to the inlet chamber and through the needle into the pulp chamber and pulp canals. The spent solution is evacuated from the pulp chamber and pulp canals through the outlet chamber.

Solutions for perioperative intraocular application by continuous irrigation during ophthalmologic procedures are provided. These solutions include multiple agents that act to inhibit inflammation, inhibit pain, effect mydriasis (dilation of the pupil), and / or decrease intraocular pressure, wherein the multiple agents are selected to target multiple molecular targets to achieve multiple differing physiologic functions, and are included in dilute concentrations in a balanced salt solution carrier.

An infusion pressure monitoring system for a phacoemulsification or vitrectomy machine to be operated by a health care provider includes an irrigation path configured to carry an irrigation solution to a surgical site and a fluid sensor configured to detect a fluid parameter in the irrigation path. An input device receives a variable fluid flow command from the health care provider commanding an irrigation fluid flow through the irrigation path at a flow rate corresponding to the command. A controller communicates with both the fluid sensor and the input device. The controller determines an expected fluid pressure value and a dynamically variable threshold pressure value based upon the variable fluid flow command.

A method and solution for perioperatively inhibiting a variety of pain and inflammation processes at wounds from general surgical procedures including oral / dental procedures. The solution preferably includes at least one pharmacological agent that is a soluble receptor tyrosine kinase, and optionally additional multiple pain and inflammation inhibitory agents at dilute concentration in a physiologic carrier, such as saline or lactated Ringer's solution. The solution is applied by continuous irrigation of a wound during a surgical procedure for preemptive inhibition of pain and while avoiding undesirable side effects associated with oral, intramuscular, subcutaneous or intravenous application of larger doses of the agents.

A fluid control device is attached to tubes carrying irrigation solution to form the system. The control device splits the flow through a fiber optic scope and a fluid control unit. The fluid control unit controls rate of flow and direction. The operator utilizing a fluid rate and flow direction control device easily controls the flow of fluid into the joint, out of the joint, or no flow. The increased flow prevents collapse of a joint space and maintains clear visualization. The fluid flow solely relies on a gravity feed by having a fluid reservoir positioned at a high point in the system. It contains no fluid pump, vacuum or electronic controller while safely and reliably performing the functions of more complex devices.

A triple natural polymer viscoelastic composition is disclosed. By combining glucosamine sulfate (''GS''), sodium hyaluronate (''HA'') and chondroitin sulfate (''CS''), the triple natural polymer viscoelastic compositions of this invention can provide a viscoelastic agent at a surgical site that not only serves as a protective agent to ocular tissues, but that can also act as an agent to alleviate pain and inflammation associated with ocular surgery. Embodiments of this invention can comprise GS combined with existing HA / CS viscoelastic agents. Embodiments of this invention can also comprise GS and CS in combination with an irrigation solution. Further, to enhance retention time at the site of an intra-articulate application of an embodiment of this invention, the following biodegradable polymers may also be included in an embodiment of the compositions of the present invention: cellulose derivatives (e.g., hydroxypropylmethylcellulose, ethylcellulose, caboxymethylcellulose, etc.), carbopol, citosan, and collagen.

The subject invention provides novel, inexpensive, and highly effective methods and devices for convenient and effective irrigation of abscesses, puncture wounds, and similar types of deep tissue wounds. In one embodiment the subject invention provides a discharge apparatus for a reservoir housing containing irrigation solution, wherein the discharge apparatus has a specifically designed nozzle for insertion into a wound opening and through which a sufficient volume of the irrigation solution can pass at an appropriate pressure.
