Chapter 15 With contributions from Dr Roxanna Zakeri Your surgical placement is likely to be one of the most demanding periods of your Foundation training. Few other specialties will give you such a pivotal role in the team. Though this may seem daunting, it will be one of the best learning experiences you will have, from which you can take multiple transferable skills relevant to any specialty you wish to pursue. In this chapter we will explore the main tasks you can expect to face in your surgical job, giving practical tips and advice to guide you in becoming a proficient, confident, multi-tasking junior surgeon. Essentially, you will be required to handle any medical issues the patient develops during their admission and escalate to the relevant medical teams as necessary. All patients undergoing elective surgery will be assessed preoperatively, usually in pre-assessment clinics a few weeks prior to surgery but also on the ward if admitted in advance. You may be involved at either or both of these stages; however, the points to consider when clerking are the same for both. Address any questions or concerns the patient may have. Although the procedural details, indication, risks and benefits should have been discussed by a surgeon in clinic, the anxiety of impending surgery may result in these being forgotten. Explain the procedure and address concerns, but if unsure, reassure them that a senior colleague will come to explain further. Do not be surprised if you have patients arrive on the morning of surgery having decided they do not want to go ahead, after all of your previous efforts! Above all, ensure that they are making a fully informed decision. Usually such changes of heart are temporary and simply require reassurance. Having said that, they are perfectly within their rights to change their minds, even if they have previously signed a consent form. In these cases, you should inform your seniors early so they can make alternative treatment arrangements and adjust the operating list as required. Check if the patient has any current/recent symptoms of viral illness, for example, cough, sore throat, diarrhoea and vomiting. Depending on the procedure planned, patient fitness and anaesthetic risks, this may be a contraindication to proceed. Notify the consultant surgeon and anaesthetist immediately if you are concerned. For a comprehensive guide to which tests to perform in different grades of surgery and patient ASA grade, consult the latest NICE guideline (Clinical Guideline 3 – Preoperative Tests, June 2003 – The use of routine preoperative tests for elective surgery). You should consider requesting the following: Check local hospital guidelines on transfusion requirements for specific procedures but the commonly requested amounts are presented in the following table. There is no evidence-based justification for routine G&S in all surgical cases; therefore, check with your consultant and local transfusion policy and send if needed. Timing of G&S requests should also be considered. Bear in mind it takes a minimum of 45 minutes for a full crossmatch, often longer in practice in a busy blood bank. Some blood banks require two separate G&S samples to be sent for each patient at separate times before they will issue type-specific blood. Check with your hospital how long preoperative blood samples are saved and valid for. On average, G&S samples are saved for 14 days; however, a history of recent blood transfusion complicates matters and will require an up-to-date sample to be taken as follows (timings may vary). To reduce the risk of aspiration during anaesthesia, patients are fasted preoperatively. Traditionally, a ‘nil by mouth from midnight’ approach was taken, but now, the general rule is no oral intake of solids for ≥6 hours prior to induction of anaesthesia. Only clear fluids are allowed within 2–6 hours of surgery, that is, water/black tea/coffee. Chewing gum and soluble mints/sweets are the equivalent of eating in terms of producing gastric juices; therefore, ensure they are avoided for ≥6 hours. Many cases have been cancelled because of missing the occult gum-chewing patient! The above timings are the absolute minimum times for elective cases. In absolute emergency, rapid sequence induction can be carried out regardless of fasting time, involving complete paralysis and maintained cricoid pressure to reduce the risk of passive gastric reflux. However, aspiration risk can still be high and rigorous oropharyngeal monitoring and suction may be needed during recovery. Factors that increase the risk of aspiration include: Obtaining consent is an art combining communication skills, surgical knowledge and perception. It takes practice and the best way to learn is to watch your senior colleagues in action. Do not think of obtaining consent as an isolated process where a patient signs a piece of paper moments before being wheeled away, though this has been known to happen in practice. It is advisable to take the time to discuss the patient’s overall management, not just this procedure, and ensure they are fully informed of the plan, including alternative treatments. Although this may have been explored prior to admission, unless the patient is aware and understands the plan at the time of surgery, consent would not be valid. Written consent alone is not legally adequate proof of consent. It takes time for these discussions, but you benefit by developing your relationship with the patient. Unless the patient objects, it is usually best to have a member of close family present during the consent process. This helps the family to understand the process and risk, and it also helps in building the therapeutic relationship that will be important for the remainder of their treatment. Before embarking on consenting a patient, consider the following: firstly, are you the right person to be obtaining consent? You should only accept this responsibility if you are performing the procedure, are able to do the procedure yourself or are satisfied that you know fully the indications and potential complications. It is still the responsibility of the operator, however, to ensure that adequate consent is given. If you are not happy signing the form, that is perfectly acceptable. Do not be pressured or rushed into doing it by seniors. The deaneries take a very hard line on this and you are likely to be specifically asked at your annual review whether you were ever put in a situation where you were asked to obtain consent at a level beyond your competency. To help with the consent process, use language that the patient can understand. The patient should have an understanding of every word that you use – do not forget that phrases such as ‘anterior, supine, intubation, etc.’ are all alien to the majority of even well-educated patients. My particular favourite is when anaesthetic colleagues tell patients they intend to paralyze them! Occasionally a little imagination and abstract analogies may be required but you must persist. Diagrams are invaluable. Practice drawing relevant anatomy and/or steps of the procedure that you can use when explaining them to patients. Alternatively, look in your department for patient information leaflets. Often they can be in different languages, ideal for when your patient does not speak English. If you feel confident to obtain consent, fill in the appropriate consent form and sign with your name, grade and date. Obtain the patient’s signature and then document in the notes what was discussed. There are many different types of consent forms. In general use a yellow consent form 1 for routine informed consent. If an adult patient lacks capacity and you are performing a procedure in their best interests, use a form 4. This does not require patient signature but relatives can sign to show they were involved in a discussion about care. The different forms available are as follows. In all cases of surgery, it is important to inform patients of: If possible, check the actual figures for risks common to the procedure in question, both in the literature and locally. Some of the common or serious risks of specific procedures are listed below. As there have been cases where the wrong side was operated on (wrong-site surgery), the UK National Patient Safety Agency and the Royal College of Surgeons have recommended the following for surgical site marking: Robust marking pro formas are encouraged to ensure multiple stages of site verification. Here is an example of one you may be expected to complete (Table 15.1). Table 15.1 Preoperative marking verification checklist For hospitals that still require juniors to book elective lists, prepare the list by the morning prior to operating day by the latest. Check when the consultant and his/her secretary require finalized details. If you continue with surgical training this will become routine for you. Things to include are: Sign, date and bleep number For booking emergency operations you should: Further to all the checks you have done so far, further perioperative checks are done according to the WHO Surgical Safety Checklist. There are three points of verification: The simple checklist shown in Figure 15.1 has proven to reduce the incidence of the most common avoidable perioperative risks and improve outcomes.
