Chapter 14 Clinical observation and Emergency Treatment for critically ill patients Emergency Section Ⅰ clinical observation Section Ⅱ Emergency Treatment for critically ill patients Organization and management of resuscitation Management of resuscitation equipments Resuscitation skills commonly used Supportive care for critically ill patients Critically ill patients Critically ill patients are those who are in serious condition, and may possibly have the danger of life-threatening at any moment. The basis to successful resuscitation is timely, comprehensive and accurate observation and recording of the patients’ condition. The key to successful resuscitation is to apply all the resuscitation techniques skillfully. The guarantee to successful resuscitation is the organization and management of rescuing work. Section Ⅰ clinical observation The purposes of clinical observation The requirements of nursing staff The methods of clinical observation Contents of clinical observation The purposes of clinical observation Providing the scientific basis to the diagnosis, treatment and nursing of diseases. Forecasting the trend and outcome of diseases. Knowing the effectiveness of treatment and medication effects on patients timely. Finding the signals of the changes of critically ill patients’ conditions, in case of the aggravation of diseases. the requirements of nursing staff rich and profound medical knowledge great responsibility acute observational ability frequent the principles of being frequent in five aspects. inspection frequent observation frequent enquiry frequent consideration frequent record the methods of clinical observation inspection auscultation palpation percussion smelling Besides the commonly used five methods above, health care givers require effective communication. Contents of clinical observation Observation of general condition Observation of vital signs Observation of consciousness Observation of pupils Observation of psychology Observation of diagnostic studies or drug treatment Observation of other aspects Observation of general condition Development and body figure Diet and nutritional status Facial features and expression Position Posture and gait Skin and mucous membrane Observation of vital signs Body temperature Pulse Respiration Blood pressure Observation of consciousness Consciousness is the comprehensive reflection of how cerebrum reacts to the environment. Disturbance of consciousness Light coma Somnolence Confusion Stupor Coma Deep coma Glasgow Coma Scale, GCS The scale comprises three tests: eyes opening (4 grades) verbal response (5 grades) and motor responses (6 grades) The highest possible GCS (the sum) is 15 (fully awake person), while the lowest is 3 (deep coma or death). If the score is less than 7 and more than 3, it’s light coma. Best eye response There are 4 grades starting with the most severe: No eye opening.......................................1 Eye opening in response to pain...........2 Eye opening to speech ..........................3 Eye opening spontaneously.................4 Best verbal response There are 5 grades starting with the most severe: No verbal response .................................1 Incomprehensible sounds ......................2 Inappropriate words ..............................3 Confused conversation ...........................4 Oriented ..................................................5 Best motor response There are 6 grades starting with the most severe: No motor response..................................1 Extension to pain ...................................2 Abnormal flexion to pain ......................3 Flexion/Withdrawal to pain ..................4 Localizing response to pain ...................5 Obeying command .................................6 Observation of pupils The shape, size and symmetry of pupils Light reaction Shrinking: the diameter of a pupil is smaller than 2mm. Bilateral pupil diminished may be seen when there are poisoning conditions of organophosphorous insecticides( 有 机磷 农药 ), chlorpromazine( 氯丙嗪 ) and morphine(吗啡). Unilateral pupil diminished may indicate the earlier stage of transtentorial hernia(小脑幕裂孔疝). Largening: the diameter of a pupil is bigger than 5mm, (mydriasis) Bilateral pupil dilated commonly is seen with the state of intracranial hypertension( 颅 内 高 压 ), craniocerebral injury ( 颅 脑 损 伤 ), Belladonna poisoning (颠茄类药物中毒) and dying. One side pupil dilated and fixed may indicate the occurrence of transtentorial hernia (小脑幕裂孔疝) which caused by same side intracranial hematoma (颅内血肿) or brain tumor. Observation of diagnostic studies or drug treatment Observation after diagnostic studies or treatment Observation of patients treated by special drugs: the effect the side effect the toxicity of medications Section Ⅱ Emergency Treatment for critically ill patients Closely knit organization Reasonable assignment Essential and perfect equipment Skilled medical workers Necessary emergency drugs Organization and management of resuscitation Resuscitation team director head nurse Formulate resuscitation plan work out the nursing plan cooperate with doctors to carry on the rescue record verify continue with the clinical observation after resuscitation and pass nursing report to the next shift nurses. attend while doctors conduct the ward round, make consultations and discuss the cases of illness.

Strictly implement the “Five Fixed” system: fixed amount fixed places to arrange fixed staff in charge disinfecting at fixed time maintenance at fixed periods Resuscitation skills commonly used Cardio-pulmonary Resuscitation (CPR) Gastric lavage Sudden cardiac arrest,SCA CPR is a combination of oral resuscitation that supplies oxygen to the lungs, and external cardiac massage (chest compression), which is intended to reestablish cardiac pump function and blood circulation. (Heart-lung resuscitation) oral resuscitation chest compression when a cardiac arrest or respiratory arrest occurs, a combined effort is made to restore or maintain respiration and circulation, artificially. The cardinal signs of a cardiac arrest unconsciousness absence of a carotid pulse apnea dilated pupils pale or cyanosed skin absence of heart sounds nil bleeding from wound compression Basic Life Support (BLS) airway breathing Advanced life support(ALS) Prolonged life support(PLS) Purpose To establish artificial circulation and respiration To circulate oxygenation blood to the vital organs to prevent permanent tissue damage Indications Cardiac arrest and/or respiratory arrest Contraindications Presence of heart beat and breathing Severe injuries to thorax or heart Severe deformity of thorax and spine Equipment chest compression board step bench blood-pressure meter Stethoscope Oral airway or face mask if available Ambu bag if available Procedures-Assess whether victim is unconscious: shaking client's shoulders gently shouting Procedures-If victim is not responsive, activate Emergency medical Services -EMS (call 120). 120 Procedures- Place the client on hard surface Place the client in supine position Take away pillow under client's head and loosen client's collar and belt Procedures-check the carotid pulse Locate it by placing two fingers in the groove between the Adam’s apple and the muscle. ★If there is a pulse ★If there is no pulse <10s If there is a pulse ventilate victim at rate of one breath every 5 seconds (10-12/min) Recheck the carotid pulse every 2 minutes If breathing resumes, observe carefully to verify continued spontaneous respiration. If there is no pulse, initiate chest compression A person in bed must be moved to the floor, or a cardiac board. Locate the position for compression Place the hands on the breastbone at the nipple line. Place another hand on top of the hand the heel of the hand Keep fingers off chest wall Extend arms and lock elbow. Maintain arms straight and shoulders directly over victim’s sternum. Press straight down on the sternum, compressing the chest 5 cm. Then release pressure, maintaining contact with skin. Give compressions at rate of 100 /min, counting “one and two and,” etc, up to 30. Procedure-- open airway head-tilt, chin-lift method a.Place palm of one hand on victim’s forehead. b.Place fingers of another hand under victim’s chin. c.Simultaneously push down on forehead and lift upward on chin. Use care to avoid pressure on the soft tissue of the throat. jaw thrust method —If head or neck trauma is suspected grasp angles of victim's lower jaw and lift with both hands, displacing mandible forward. If victim is not breathing, administer artificial breathing Mouth-to-mouth Mouth-to-nose Mouth-to-mouth/ nose Mouth-to-mouth resuscitation a. Pinch nostrils together. b. take a deep breath and place mouth over the victim’s mouth, forming a tight seal. c. Blow two full breathes into the client's mouth (each breath should last 1 second); allow the client to exhale between breathes by loosing the nose. Mouth-to-nose resuscitation Keep victim's head tilted with one hand on forehead. Use another hand to lift jaw and close mouth. Seal nurse's lips around victim's nose and blow. Allow passive exhalation. After 2 full ventilations, reposition hands correctly, give 30 compressions. The ratio of compressions to breath is 30 to 2 for one or two rescuer. After the 5 cycle CPR, check carotid pulse and resume CPR if absent. Recheck pulse every few minutes, but do not interrupt CPR for more than 10s. Pulse should also be checked if signs of recovery such as movement, swallowing, or returning facial color occur. If pulse is present, continue ventilations every 5s without compressions if the client does not resume breathing. Continue CPR until heartbeat and breathing are restored, EMS arrives, or victim is pronounced dead by a physician. If heartbeat and breathing resume, continue to observe and arrange for transport of victim to hospital. Gastric lavage is a medical approach for therapeutic irrigation of stomach by inserting a gastrolavage tube to stomach via mouth or nasal cavity, through which certain quantity of irrigating solution is pumped into stomach by gravity, siphonage, and negative pressure suction. Purpose Acute toxicosis, especially within 6h after it Detoxification: Clear the stomach contents or other harmful substance. Alleviate the edema of stomach mucosa: Wash out food in stomach; Alleviate stimulation, edema and inflammation of stomach mucosa. preparations needed before some operation or diagnostic studies.
