Theoretical skills can be learnt in the classroom, from written material or computer programmes. The acquisition of practical skills, however, requires the use of training manikins. It is impracticable as well as potentially dangerous to practise these procedures on human volunteers. Adult and paediatric manikins are available from several manufacturers worldwide; this chapter concentrates on those generally available in the United Kingdom. Manikin selection: general principles Training requirements The growing number of different manikins available today can make choosing which manikin to purchase a complex process. Manikins are vital for learning practical cardiopulmonary resuscitation skills The most important question to ask initially is: which skills need to be acquired? This will obviously depend on the class under instruction; the requirements of a lay class will be quite different from those of professional hospital staff learning advanced life support skills. For large classes it may be better to maximise the practical hands-on exposure by investing in several cheaper With all manikins, realistic appearance, manikins rather than rely on one or two expensive, more accurate anatomical landmarks, and an appropriate response to any attempted complex models. Models vary greatly in sophistication, but most provide some qualitative indication that technique is adequate, such as audible clicks when the depth of chest compression is correct. Some manikins incorporate sensors that recognise the correct hand position and the rescuer’s attempts at shaking, opening the airway, and Resuscitation skills that can be practised palpation of a pulse.

Some care is required, however, and the “skin” should not be permanently marked by lipstick or pens or allowed to become stained with extensive use. Many currently available manikins have replacements available for those components subject to extensive wear and tear. This is particularly true for the face, which bears the brunt of damage and where discoloration or wear will make the manikin aesthetically unattractive. A carrying case (preferably rigid and fitted with castors for heavier manikins) is essential for safe storage and transport. Cross infection and safety To minimise the risk of infection occurring during the conduct of simulated mouth-to-mouth ventilation the numbers of Manikins can be students using each manikin should be kept low and careful used for a attention should be paid to hygiene. Students should be free of variety of communicable infection, particularly of the face, mouth, or training exercises respiratory tract. Faceshields or other barrier devices (see Chapter 18) should be used when appropriate. Manikins should be disinfected during and after each training session according to the manufacturer’s instructions.

The author uses a combination of inside out nonabsorbable sutures and absorbable meniscal arrows super p-force 160mg generic erectile dysfunction in 40s. The combination of vertical sutures in the middle of the meniscus super p-force 160mg overnight delivery erectile dysfunction drugs cost comparison, and bioabsorbable arrows in the posterior region is shown in Figure 6. The video on the CD includes a demonstration of the inside out, zone-specific technique of meniscus repair. The Technique of the Excision of a Bucket-Handle Tear of the Meniscus Some of the preparation is the same for this procedure, as for the pre- vious procedure. There may be a lot of synovium and fat pad that needs to be removed with a shaver in order to visualize the meniscus. Hamstring Graft Reconstruction Techniques Often the first view will be a “white out. The physician should look over the displaced frag- ment to assess the size of the remaining rim to determine if it is suit- able for repair. Step 2: The Reduction of the “Handle” First, the physician should reduce the displaced fragment (Fig. This is necessary to see the ante- rior attachment to cut the bucket handle clean from the rim. Step 3: Cutting the Posterior Attachment The posterior attachment is divided first. If the anterior attachment were cut first, the main fragment might displace into the posterior com- partment, necessitating a posterior portal to remove it. Step 4: Insert the Scissors The scissors are inserted through the medial portal, while visualizing through the anterolateral portal (Fig. To cut the anterior attachment, the scissors are brought in through the anteromedial portal (Fig. If not, the scope is placed in the anteromedial portal and the scissors brought through the anterolateral portal. Step 5: Removing the Fragment from the Joint A grasping instrument is used to remove the loose fragment (Fig. Sometimes, it is better to leave a small strand still attached so that the fragment does not migrate around the joint. It is also better to grasp the fragment on the end, so it comes out of the portal easily. If the physician grasps it in the middle, it must fold over and is harder to remove through a small portal. Harvest of the Hamstring Graft Skin Incision An oblique 3-cm skin incision is made over the pes anserine (Fig. This should start 1cm medial to the tibial tubercle and head postero- medial. The physician should plan to harvest the graft and drill the tibial tunnel through this incision. Exposure of the Tendon The physician should identify the superior border of the pes and incise the fascia. Then, continue the incision medially, in a hockey stick fashion, down the tibia to remove the attachment site. Look for the most inferior tendon, the semi-t, lift it up with the tip of the scissors or a kocher. Tendon Release The first step is to free the distal end of the tendon with the scissors. Many of the bands can be released with the traction and by blunt finger dissection. The main band that goes to the medial head of the gastrocnemius will usually have to be cut with the scissors (Fig. Pull firmly on the tendon and cut away from the tendon (to avoid cutting the tendon with the scissors).

The guide wire is placed in the correct position and visualized before drilling generic 160 mg super p-force with amex erectile dysfunction gene therapy. The screw would force the bone plug of the graft out the back of the tunnel trusted 160 mg super p-force erectile dysfunction what kind of doctor, and loss of fixation would result. Solution When the back wall blowout is recognized, change from interference screw to Endo-button fixation. Another solution is to use the two- Intraoperative Complications 167 Figure 9. It is also possible to advance the screw and graft farther up into the femoral tunnel. Visualize posterior fringe and use a push/pull drill to make an initial footprint. If this is not blowing out the posterior wall or is not too anterior, then the drill bit can be advanced 35mm up into the femur. The footprint of the femoral tunnel position is made before committing to drilling the femoral tunnel (Fig. Overdrilling K-Wire Problem When the drill bit fails to progress, it may be that the bit is drilling into the wire (Fig. To determine if this is the problem, pull the drill back, remove the K-wire, and insert a new one. Intraoperative Complications 169 Solution The solution to the problem is to recognize it early and avoid completely drilling through the wire. If the wire is cut off in the middle of the tunnel, it is hard to retrieve. Prevention To prevent drilling the wire, watch the drill and piston over the wire to make sure that it is following the path of the wire. Piston Drilling to Follow the K-Wire: Lack of Visualization—The “Red Out” Problem Figure 9. The arthroscopic stack of equipment that is necessary to perform arthroscopic surgery, including the fluid pump. Solution The remedy for the lack of visualization is the following: • Increase the flow of the pump (Fig 9. Loss of Fixation: Bone Plug Cut Off the Graft Problem The screw may cut the tendon off the bone plug if the screw does not follow the direction of the tunnel (Fig. Put the tibial bone plug in femoral tunnel and fix this with an interference screw. On the other end, use a Krackow suture in the cut tendon end and tie over a button on the tibia (Fig. The sutures are placed in the tendon end of the graft and tied over a button or post. Prevention To prevent the screw from damaging the graft, visualize the angle of the screw during insertion. The screw should be parallel to the graft and convergent in the femoral tunnel (Fig. It also helps to make a low anteromedial portal to insert the screw straight up the tunnel. The insertion of the BioScrew into the femoral tunnel, parallel to the graft. Loose Fixation of Interference Screws Problem If the screw is not put parallel to the tunnel, it may result in posterior penetration of the femoral tunnel. The appropriate size of screw, one that gives good purchase on the graft, must be used. Solution Use a two-pin passer to place the femoral screw in the femoral tunnel (Fig. If the guide wire is in the tunnel, the screw should follow the guide wire. Intraoperative Complications 173 Prevention In soft tissue graft fixation, use a screw that is the same size in the femoral tunnel and one size larger in the tibial tunnel.

Failure to achieve an output despite external pacing is only a temporary measure good electrical capture on the ECG is analogous to electromechanical dissociation buy generic super p-force 160mg online erectile dysfunction treatment in dubai, and an urgent search for correctable causes should be made before concluding that the myocardium is not viable discount 160mg super p-force with visa impotence in young men. When the external pacing unit is not part of a defibrillator, defibrillation may be performed in the conventional manner, but the defibrillator paddles should be placed as far as possible from the pacing electrodes to prevent electrical arcing. Invasive methods Temporary transvenous pacing A bipolar catheter that incorporates two pacing electrodes at Chest compression can be performed with the distal end is introduced into the venous circulation and transcutaneous pacing electrodes in place. Pacing is performed once a The person performing the compression is not at risk because the current energies are stable position with an acceptable threshold has been found, very small and the electrodes are well usually at a site near the right ventricular apex. It is usual practice, however, to turn is usually used to guide the placement of the pacing wire, but the unit off should CPR be required when this is not easily available flotation electrode systems, such 83 ABC of Resuscitation as the Swan-Ganz catheter, that feature an inflatable balloon near the tip offer an alternative method of entering the right ventricle. A central vein, either the subclavian or jugular, is cannulated to provide access to the venous circulation. Manipulation of the catheter is easier than when peripheral venous access is used, and the risks of subsequent displacement are less. Full aseptic precautions must be used because the pacemaker may be required for several days and infection of the system may be disastrous. Once a potentially suitable position has been found the pacing catheter/electrode is connected to a pulse generator and the pacing threshold (the minimum voltage that will capture the ventricle) is measured. This should be less than 1 volt, and the patient is paced at three times the threshold or 3 volts, whichever is the higher. If the threshold is high, the wire should be repositioned and the threshold measured again. Regular checks should be undertaken—a rise in threshold will indicate the development of exit block (failure of the pacing stimulus to penetrate the myocardium) or displacement of the pacing wire. Defibrillation may be performed in patients fitted with a temporary transvenous pacing system but it is important that the defibrillator paddles do not come into contact with the temporary pacing wire and associated leads, and that electrical Temporary arcing to the pacing wire through conductive gel does not pacing wire in right ventricle occur. Permanent pacemakers Modern permanent pulse generators are extremely sophisticated devices. Most use two leads to enable both sensing and pacing of the right atrium as well as the right ventricle. This allows both atrial and ventricular single-chamber pacing and dual-chamber pacing, in which both pacing and sensing can take place in the atrium and ventricle to allow more physiological cardiac stimulation. Some devices also increase the rate of pacing automatically to match physiological demand. Modern generators are programmable, whereby an electromagnetic signal from an external programming device is used to modify one or more of the pacing functions. The optimal mode for the individual patient may be selected or the feature may be used to diagnose and treat certain pacing complications. External programming allows modifications of pacing characteristics or the incorporation of features that had not been anticipated at the time of implantation. Pulse generator and pacing wire Defibrillation and permanent pacemakers The sophisticated electronics contained in modern pulse generators may be damaged by the output from a defibrillator, although a protection circuit contained in the generator helps to reduce this risk. Defibrillator electrodes should be placed as far as possible from a pacemaker generator, but at least 12. Chest radiograph If the generator has been put in the usual position below showing the left clavicle, the conventional anterolateral position may be biventricular pacemaker with suitable. After successful resuscitation the device should be leads in the right checked to ensure that the programming has not been ventricle, right affected. This complication may not become apparent until some time after the shock has been given. For this reason the pacing threshold should be checked regularly for several weeks after successful resuscitation. The implantable cardioverter defibrillator The implantable cardioverter defibrillator (ICD) was developed for the prevention of sudden cardiac death in patients with life- Defibrillation by an ICD threatening ventricular arrhythmias, particularly sustained VT or VF. Observational studies and recent prospective studies have shown their effectiveness. Technological advances have been rapid and modern cardioverter-defibrillators are much smaller than their predecessors. One or more electrodes are usually inserted transvenously, although a subcutaneous electrode is sometimes used.
