Using a punch, push the detent from its recess and rotate the spring plate so the detent is just above the frame. The slide stop spring is the only spring on the left hand lever assembly.Ī screwdriver can be used to either push or pull the C-clip (retaining ring) from the slide stop shaft. Caution: These instructions are for reference only and should be used at your own risk.ġ: Remove magazine and verify pistol is unloadedĢ: Insert safety takedown flag or 22LR case between recoil guide rod and frameģ: Remove recoil guide plug and move slide to rearĤ: Remove guide rod and spring from slide The pistol used to develop these instructions was a 2206TGT there may be slight variations in the process for other models. The following instructions outline the process steps to disassemble and reassemble the Smith & Wesson 422/622/2206/2213/2214 series of 22LR pistols. ***Custom tools may be used, but they increase the risk of damaging the barrel nut and/or muzzle crown (examples: socket ground down to only leave engagement teeth, wide screw driver with center ground out for muzzle clearance, back of butter knife with notch ground out for muzzle clearance, needle nose pliers, etc.) **An empty 22LR case can be used to restrain the recoil guide rod *These screws have a tendency to work lose and fall off Conclusion: From the observation in this study it can be stated that the low dose aspirin therapy can be continued prior to extraction procedure in the oral cavity without the fear of excessive intra-operative and post operative bleeding.422/622/2206/2213/2214 Disassembly - Reassembly Instructions However, the blood loss in patients during the first appointment was easily managed using local hemostatic measures which prevent any grave bleeding complication. The difference was statistically significant with a t – value of 3.2. Results: The mean blood loss at the first appointment for the patients was 5.78 ml while it was 1.18 ml at the second appointment. The bleeding time, clotting time, platelet count and INR were measured preoperatively at both the appointments and the amount of blood loss during the procedure was assessed. Each patient acted as a control for himself, wherein an extraction was performed on a patient when aspirin was not discontinued and a second extraction after discontinuing aspirin for 72 hours prior the procedure. Methodology: The study samples consisted of 25 patients receiving 100 milligrams of aspirin daily and were scheduled to undergo dental extractions. The purpose of the study is to analyze if there is a need to discontinue low dose antiplatelet therapy before dental extraction. This is also stated in the guidelines of the American Heart Association.īackground and purpose: Aspirin is the most frequently used preventive and therapeutic drug for patients with cardiovascular diseases because of its antiplatelet property, which might lead to the risk of excessive bleeding during the surgery. Conclusion: Reviewing most of the dental and medical literature, it can be concluded that there is absolutely no need to discontinue anti-platelet therapy for any ambulatory dental procedure, and even if the practitioner wishes to discontinue, it should not be for more than 3 days. But in both the groups, bleeding and clotting time remained within normal limits. Similarly, the clotting time increased in group B patients and decreased in group A patients. Results: Chi‑square test revealed that the bleeding time increased (3.8 ± 0.75) in group A patients continued with the aspirin therapy where as group B discontinued aspirin. Bleeding time and clotting time were recorded for evaluation by Chi‑square test. After checking all the vital signs, the extractions were carried out. The patients were randomly divided into aspirin continuing group (group A) and aspirin discontinuing group (group B). Materials and Methods: Two hundred patients aged between 50 and 65 years who were indicated for dental extraction for endodontic reason were selected from the outpatient department of Oral and Maxillofacial Surgery. Aim: The aim of the study was to evaluate the influence of aspirin on post‑extraction bleeding in a clinical setup.
