Active clinical trials for "Dilatation, Pathologic"

Justification. Pain control is still an issue for women undergoing second trimester abortion procedures. The investigators propose a randomized controlled double-blinded trial evaluating the use of adjunct gabapentin versus placebo in addition to moderate sedation during D&E. The investigators hypothesize that 600 mg oral gabapentin administered pre-operatively at the time of cervical preparation initiation will improve intra-operative pain control. The investigators also hypothesize that it will improve pre- and post-operative pain, anxiety, nausea, vomiting, and overall satisfaction with pain management during D&E. To test the hypotheses the investigators plan to enroll 130 participants who will be randomized 1 to 1 to receive either 600 mg gabapentin or placebo at the initiation of cervical preparation.

This study evaluates the use of Transcutaneous Electrical Nerve Stimulation (TENS) as a method of pain control during osmotic dilator insertion prior to dilation and evacuation. Half the group will have an active TENS unit and half will have a sham or placebo TENS unit.

The objective of this study is to evaluate safety and effectiveness of the Lacrosse NSE ALPHA coronary dilatation catheter during PCI in subjects with stenotic coronary arteries.

According to chewing gum can promote the recovery of gastrointestinal function, it is used as an intervention measure for patients after lumbar surgery to evaluate the effect of chewing gum on improving abdominal distension of patients after lumbar surgery, so as to provide basis for the application and promotion of chewing gum in lumbar postoperative nursing

The purpose of this study is to evaluate the effectiveness of using riboflavin and UV light to treat progressive keratoconus or post-refractive corneal ectasia.

Prospective, randomized, single site study to determine the safety and effectiveness of performing corneal collagen cross-linking (CCCL)using riboflavin and UVA light in eyes with corneal ectasia or progressive keratoconus.

Prophylactic tranexamic acid has shown been shown to reduce maternal mortality from postpartum hemorrhage with no adverse effects, but has not been studied to reduce bleeding complications with dilation and evacuation (D&E). We propose a randomized, double-blinded, placebo-controlled pilot study to determine whether routine use of intravenous (IV) tranexamic acid will decrease the need for interventions to control bleeding at the time of D&E at 16 to 24 weeks gestation.

The objectives of this study are: To evaluate the efficacy of Nyxol (phentolamine mesylate ophthalmic solution 1%) to expedite the reversal of pharmacologic mydriasis To evaluate the safety of Nyxol To evaluate the effect of Lumify® to suppress conjunctival hyperemia (redness) potentially associated with administration of Nyxol

We investigated the use of a copper sulfate eye drop (IVMED-80) for the treatment of keratoconus. Preliminary laboratory data shows that the addition of copper sulfate increase crosslinking of the structural proteins of the cornea thereby halting the progressing corneal thinning and bulging seen in keratoconus. We conducted a Phase 1/2a study to evaluate the safety and preliminary efficacy of a 6-week and a 16-week regimen using IVMED-80 and studied its impact on ocular safety and the change/progression in patients' vision and clinical measurements.

Clinical study on safety and efficacy of ZENFlow™ drug-eluting PTA balloon dilatation catheter in the treatment of iliac, femoral and popliteal artery stenosis or occlusion
