In addition cheap 100mg fluvoxamine overnight delivery anxiety symptoms all the time, the patient is intubated due to a severe pulmonary contusion that has resulted in a signiﬁcant hypoxemia cheap fluvoxamine 50mg fast delivery anxiety eating. As the nurse obtains initial vital signs purchase fluvoxamine 100mg with mastercard anxiety nos, she tells you that his heart rate is 120 beats per minute and his blood pressure is 90/50mmHg. Case 2 A 69-year-old woman has just arrived from the operating room after undergoing a sigmoid colectomy with Hartmann’s pouch and an end colostomy. As the surgeon drops off the patient in your care, he com- ments that there was a large amount of stool contamination in the abdomen that seemed to be present for several days. Due to a large amount of intraoperative ﬂuids, the anesthesiologist decided to keep the patient intubated. Surgical Critical Care 83 Introduction It is not uncommon for a medical condition or illness to involve mul- tiple organ systems. In addition to the primary anatomic insult and the problems that result, a cascade of physiologic derangements may occur that involve multiple, seemingly unrelated, organ systems. This usually is the case in the surgical critical care patient, where an initi- ating event, such as major trauma, burns, or infection, along with any premorbid conditions, results in a life-threatening situation that requires an understanding of complex physiologic interactions. The resul- tant condition is that of capillary leak, myocardial depression, and massive ﬂuid balance changes. As with any discipline, a thorough history and physical examina- tion are imperative in beginning to understand the process or processes at hand. This includes any premorbid conditions, such as heart or lung disease, as well as details of the latest insult that initiated the process at hand. Elements, such as injuries from a traumatic event, details of a surgical procedure, or the likely focus of infection, are helpful in deter- mining what steps need to be taken to provide appropriate support to the patient. In addition, conditions that are immediately life threatening are addressed and treated in a systematic approach. History and Physical Examination History As stated earlier, knowing the patient’s history (Table 5. As in the trauma patient in Case 1, identiﬁcation of all injuries is crucial in helping avoid potentially hazardous therapeutic 84 J. Airway Evaluation Ensure airway is patent Problem Obstruction from foreign body Anatomic obstruction (tongue) Physiologic obstruction (vomitus, secretions) Therapy Endotracheal/orotracheal intubation Surgical airway (cricothyrotomy/tracheostomy) 2. Breathing Evaluation Ensure air is moving equally between both lungs Problem Tension pneumothorax Hemothorax Lung or lobar collapse Therapy Needle thoracostomy Tube thoracostomy 3. Physical Examination In this technologic age of invasive monitoring and other advanced diagnostic modalities, it is easy to overlook the physical examination in the evaluation of the critically ill patient. By merely touching a patient and noting the temperature of the skin, one can diagnose that a patient is in shock and even determine the type of shock, such as in the patient with mottled, cool skin who is in hypovolemic shock. This is the situation in Case 1, where the cool, pale, mottled skin should alert the clinician that a derangement in the patient’s hemodynamics exists. Surgical Critical Care 85 The loss of breath sounds over a lung ﬁeld in a mechanically ventilated patient who experiences a sudden drop in blood pressure can reveal a tension pneumothorax. In this situation, waiting for further diagnostic tests may prove to be detrimental and may result in the patient’s death. A systematic approach to the physical exam, especially when con- ducted the same way for each patient, ensures that no elements of the exam are neglected or missed. Depending on the examiner’s pref- erence, this usually is carried out anatomically from “head to toe” or using a systemic approach, such as commencing with the neurologic system and ending with the musculoskeletal system (Table 5. Diagnostics and Management Because critically ill patients frequently have dysfunction involving multiple organ systems, diagnostic measures and subsequent thera- pies are directed at the system involved. Not uncommonly, the treat- ment of one system has an effect on other organ systems. This complex nature of the interactions between organ systems adds an extra challenge to the intensivist.

Although virtually all organ systems, from the endocrine to the immunologic, are affected in some manner, those that are treated most commonly by the intensivist are the cardiovascular, pulmonary, and renal systems. Since this chapter is designed to provide a general overview of surgical critical care, these three organ systems are the primary focus of discussion. A few of the elements of the physical exam that should be evaluated and documented. General Abdomen Level of alertness Bowel sounds Glasgow coma score Diarrhea Movement of extremities Distention Blood (upper or lower) Head, ears, eyes, nose, and throat Scleral icterus Skin Mucous membranes Turgor Jugular venous distention Temperature Peripheral edema Heart Capillary reﬁll Rhythm Pulses Rate Murmurs Lungs Character of breath sounds Coarse Rales Diminished Secretions 5. Surgical Critical Care 87 Cardiovascular Dysfunction Shock is deﬁned as the body’s inability to maintain adequate perfu- sion at the cellular level. Despite the etiology of the shock state, it is the failure of the cardiovascular system to provide this perfusion. Details on the types of shock—hypovolemic/hemorrhagic, cardio- genic, septic, neurogenic, spinal, anaphylactic—are described in Chapter 7. Determination of the type of shock is very important because treatment strategies may differ depending on the etiology.
If you don’t think that the threat is gone order fluvoxamine 100mg with amex anxiety 3rd trimester, then your body begins to not work as well generic fluvoxamine 100 mg fast delivery anxiety otc medication, bit-by-bit discount fluvoxamine 50mg on-line anxiety 5 things images, until eventually you’ll need a doctor. Mika, my patient from Thailand, for example, grew up with very deadly snakes in her home country and has been afraid of them since childhood. What Mika thinks of as stressful, in this case the sight of a snake, Larry thinks of as fun or interesting. So if stress is dependent on your thoughts about something, let’s take a look at thoughts, what they are and where they come from. Some insights into how your mind works can help you better manage the stress in your life. I’m going to lead you through some exercises that will open the door to understanding your own thought processes. This is a step-by- step journey of personal discovery that will give you an understanding of your own mind, the driver of your actions. Further, 90% of these thoughts are the same repetitive notions playing over and over. You’re constantly thinking, but most people are not consciously 11 12 • Mindfulness Medication aware of the type of thought passing through, how often it comes around, or what triggers that particular thought. Your mind is like a popcorn machine, constantly popping up thoughts, but you’re only consciously aware of a small percentage of them. Even if the thoughts seem to be something along the lines of the following: • “This is stupid. There are countdown timers available online, as various apps, or you can set an egg timer, H watch, or cell-phone timer. As you begin to observe your mind, you’ll notice that it’s always active and that it tends to say the same things over and over again. You probably get so caught up in your thoughts, just by force of habit, that even when you’re sitting silently you’re not really at rest. Once you start looking in on your thoughts you’ll probably notice that most of them seem to be about reliving the past, or planning for/imagining the future. When a thought pops up, I want you to name the time period when it seems to be occurring. The future hasn’t happened and therefore doesn’t exist as yet and the past has already gone by and therefore also doesn’t exist in the here and now. The present, this very moment, is the only time that you have any real control over. If your thoughts tend, as most do, to the future or the past, you’re missing out on a lot of the right now. You’re generally not fully present to the beauty of the only moment in time that truly exists! Another aspect of thought is that it’s largely concerned with judging, comparing and criticizing. Your mind is constantly evaluating every external and internal situation that you encounter. This time you’re going to pick a word that basically describes what the thought is about as it happens. Say something to yourself like 14 • Mindfulness Medication criticizing, or planning, or worrying, or judging, or remembering. The more familiar you are with your own mind, the easier it will be for you to intervene in your stress responses. Now that you’re getting a bit more familiar with your own mind, let’s try a few more experiments. If a different thought arises, other than mentally watching your breath-cycles and counting them, then start right back at the beginning at one. It’s important that you really try to do all of the experiments and practice suggestions in this book. Give this breath exercise a try right now and then return to the book when you’re through. Sometimes I can’t get beyond one or two breath-cycles before another thought pops up! Your mind is constantly thinking and as amazing as it is, you probably can’t even maintain your concentration for ten breaths. It can be very difficult for you to develop the concentration to be mentally present and fully aware of what’s going on in the here and now. Your mind is like a little hummingbird, flitting from one sensation, thought or perception to the next.

Exhibit 9-2 describes several widely may be a more accurate sign of tampering, available immunoassays. Similar policies can be drugs in specimens before these drugs can be developed for oral-fluid testing. Purpose Urine samples are collected and tested to assist in stabilizing a patient on the proper dosage of methadone or buprenorphine. Drug test results may suggest that a patientís dosage needs adjustment or that a more intensive level of care is need- ed. Positive drug tests alone do not confirm that a patient is not engaged in treat- ment or is not in compliance. Drug tests are not used to punish patients or as the sole reason to discharge them from treatment. A patient is not told when he or she will be asked to provide a urine sample so that a more accurate assessment of drug abuse patterns can be made. The urine is tested for several drugs of abuse and for the presence of treatment medication. This type of testing helps distinguish ingested methadone from methadone that has been added to a urine specimen as an adulterant. Patients may refuse to provide valid urine specimens for many reasons but are encouraged to provide them. If a patient refuses to provide a specimen, then urine is collected on the next dosing appointment. If a patient fails to provide a valid specimen at the next appointment, a review of take-home dosages and progress in treatment takes place and may result in more frequent required clinic visits. W hen patients refuse to provide samples, the counseling, nursing, and medical staffs are notified and consulted. Procedure The following guidelines for observing or temperature-monitoring urine specimens help increase the validity of each sample. A patient is asked to wash and dry his or her hands before and after giving samples to prevent urine contamination. To the extent possible, staff members ensure that patients do not conceal falsified urine specimens on their persons. A wide-mouth collection container may be used and the contents then transferred to a smaller container. If a patient is unable to provide a urine specimen, he or she is asked to drink plenty of water. Special considerations are given to patients with health problems that interfere with urination, including renal failure, neurological disorders, and paruresis. Any patient who still is unable to provide a urine sample must be pre- pared to give the sample on the following day. If a patient refuses to provide a sample, he or she must be referred to a counselor. After a clinical review, the treatment plan and the frequency of clinic visits may be modified.
