背景：
選擇性全膝關節置換術 (TKR) 和全髖關節置換術 (THR) 後的急性疼痛控制通常很差，並且與長期持續性疼痛障礙有關。中度至重度疼痛通常在醫療程序後的最初 48 小時內進行，需要不同的疼痛方法，例如持續控制無痛和多模式鎮靜無痛。局部浸潤麻醉（LIA）策略是目前解決圍手術期不適感的一種既定方法；儘管如此，到目前為止，我們認為已經有詳細的衝突證據。在一項正在進行的 29 項檢查探索 LIA 在 TKR 中的應用的調查中，LIA 發展成為一種改善疼痛控制的受保護程序（Gibbs DMR 2012）。我們建立了 LIA 方法，結合關節內導管，允許注射新型混合物 (NM) 在術後持續混合。預防性止痛是一種抗傷害治療，是在醫療程序之前開始的治療，目的是防止醫療程序期間發生的割傷和火燒傷引起的疼痛加劇。除了在醫療程序之前進行指導之外，還可以在術後早期使用預防性止痛。這種防禦性影響是透過傷害性框架上先發制人地消除疼痛而產生的。為了緩解疼痛感，文字記錄了一些方法，包括藥物和課程。
關節置換醫療手術被認為是最痛苦的骨科技術之一。這種痛苦的方法是在重大關節置換醫療手術後缺乏和沒有充分獎勵的術後折磨的後遺症。這種痛苦的場景必須妥善處理，因為這不僅從根本上拖延了修復過程，而且還導致了其他不便的擴大風險。如果不及時處理或沒有合理的方法，這些術後痛苦的場景可能會演變成持續的折磨，從長遠來看，這會延長住院時間和費用。為了緩解不適而進行的全程長途旅行在進行醫療程序之前就開始了。關節手術後達到長期緩解不適和實際復原的一個重要前提是在工作期間充分消除疼痛。關節手術後取得有效效果的重要角度之一是早期關節準備並開始非侵入性治療。每年都會出現一些新的藥物和新的手術來減輕手術後的痛苦，但大多數患者在手術後最終會經歷巨大的痛苦，這種痛苦往往會發展為持續的痛苦。
關節鏡膝關節手術在現今的骨科中已逐漸廣為人知。無論如何，復用後的膝關節折磨委員會，包括早期幫助和術後無痛苦的考慮，對一些臨床醫生來說仍然是一個考驗。時不時地，折磨董事會本身已經成為董事會作為育兒方法的必要條件。對某些患者來說，膝關節置換術後的頑固痛苦仍然是一個不確定的問題。折磨被認為是一種異常情緒化的事件，因為每個人都有不同的認知和痛苦邊緣。更重要的是，因此，事實證明很難使特定醫療程序的任何疼痛系統正常化。造成膝關節疼痛的因素很多，包括關節腔遊離敏感點、滑膜組織、前脂肪墊的加重。
The point of neighborhood penetration is to anesthetize sensitive spots in a limited territory of tissue by the infusion of neighborhood sedatives close by. This stands as opposed to fringe nerve obstructs, in which nerve axons are the objective and the infusion may occur in a region expelled from the careful site (eg, brachial plexus hinder for hand medical procedure). The profundity of the region to be worked on commonly decides the necessary degree of invasion. For shallow skin methods, for example, stitching of slashes and skin biopsies, subcutaneous or intradermal penetration is adequate. Increasingly broad tasks may request invasion into muscle, belt, and other profound tissues. Two general methodologies exist for anesthetizing skin and subcutaneous tissue. The first includes infusing neighborhood sedative legitimately into the line of cut and close by tissues, successfully flooding the individual nearby sensitive spots to deliver sedation. This can be exceptionally successful, yet may require huge volumes of neighborhood sedative to accomplish total inclusion.
Aims and Objectives:
In this study we find out the results on our experience using LIA in addition to the Novel Techniques and Proprietary NM developed in Leeds-Bradford and infiltrated at 4-5 mls/hour for 48 hours post surgery.
Materials and Methods:
Between October 2013 and October 2015, 62 patients undergoing primary TKR were prospectively followed up. Three groups of patients were studied. All patients studied had spinal anaesthesia (SA) with 300-400mcg diamorphine.
Group 1. GA. No LIA and no NM. 20 patients.
Group 2. SA plus NM for 48 hours post operatively with catheter placed anteriorly under the patella. 21 patients.
Group 3. SA plus LIA plus NM for 48 hours post operatively with catheter placed posteriorly in the knee joint. 21 patients.
Between June 2011 and July 2014, 173 consecutive patients undergoing primary THR using the posterior approach were also prospectively followed up.
Results and complications:
The patients without LIA or NM required more morphine in the initial 12 hours postoperative period than different gatherings. 70% (n=14) of these gathering 1 patients required 10mg morphine following TKR contrasted with just 2% (n=1) of patients requiring 10mg of morphine when LIA and NM were utilized. The expanded morphine necessity proceeded for 48 hours postoperatively in bunch 1, while none of the patients in bunches 2 or 3 required morphine following 36 hours. Factual investigation uncovered no distinction of morphine necessities with various catheter situation. Less patients experienced sickness and heaving or urinary maintenance in the gathering with LIA and NM (p-esteem <0.05, Mann-Whitney test). There were no contaminations DVT or different difficulties in any of the gatherings.
Conclusion:
這項研究表明，接受 TKR 治療的患者在 48 小時內接受 LIA 和 NM 治療後，在此期間所需的嗎啡量顯著減少。這種優勢一般在手術後的最初24小時內開始，並維持48小時。與其他組別相比，同時使用 LIA 和 NM 時，需要鎮靜止痛的患者較少。對於需要使用高達 20 毫克嗎啡的患者，最值得注意的中心性是在 0-12 小時（χ2(2) = 46.713，p = 0.000）；需要使用 30 毫克嗎啡的患者為 0-12 小時（χ2(2) = 46.310，p = 0.000）。
