and severe hypercarbia exerts a negative ionotropic effect on the heart and reduces left ventricular function. 2,3 The extent of hemodynamic changes associated with the creation of pneumoperitoneum depends on the intraabdominal pressure attained, volume of carbon-dioxide absorbed, and patient’s intravascular volume. Frequent complications associated with pneumoperitoneum includes subcutaneous or mediastinal emphysema, pneumothorax, hypoxemia, hypotension carbon dioxide embolism cardiovascular collapse, and cardiac arrhythmias. 4 There are studies, which have concluded that these adverse effects can be minimized by use of low pressure for pneumoperitoneum instead of the standard or high-pressure pneumoperitoneum. 5,6 In our study, we attempted
Because the PCO2 levels are too high the body is not getting the adequate amount of oxygen. This means the oxygen-carrying hemoglobin is not working properly do to the excessive amounts carbon dioxide causing respiratory acidosis.
The patient may have a hard time breathing because she is in pain after having surgery. Since they patient doesn’t want to breath due to the pain it can cause atelectasis and later sepsis if not treated in time. It would be important to teach the patient about splinting and to use an incentive spirometry in order to help her be able to breath. Another risk factor for the patient not being able to oxygenate would be hypovolemia since there is less blood volume which can also lead to less oxygen being able to travel in the blood or able to perfuse throughout the body.
-Use of indiscriminate sedatives, benzos, and opioid’s, especially in post-op patient who retains Co2, may suppress the ventilator drive and lead to respiratory failure
A low partial pressure of oxygen (PaO2) suggests that a person is not getting enough oxygen; Metabolic acidosis->Kidney failure, shock, diabetic ketoacidosis
Both rapid, shallow breathing patterns and hypoventilation effect gas exchange. Arterial blood gases will be monitored and changes discussed with provider. Alteration in PaCO2 and PaO2 levels are signs of respiratory failure. Patient’s body position will be properly aligned for optimum respiratory excursion, this promotes lung expansion and improved air exchange. Patient will be suctioned as needed to clear secretions and maintain patent airways. The expected outcome is that the patient’s airway and gas exchange will be maintained as evidence by normal arterial blood gases (Herdman,
All patients were followed with pulmonary artery catheters and invasive blood pressure. After orotracheal intubation, patients were ventilated with intermittent positive pressure with a tidal volume of 8 mL / kg, final expiratory positive pressure of 5 to 8 cmH2O and FiO2 of 60 to 100% to maintain arterial oxygen saturation above 95%.
Suctioning resulted in moderate to large amounts of white sputum. The patients wife stated that he had been suffering from a cold for one week prior to admission. Therefore an increase in PEEP (Hi and Lo) was required to recruit the alveoli and aid in good gas exchange. (Dellinger at al, 2007) It is recommended that positive end expiratory pressure is set to avoid extensive lung collapse on expiration. (Dellinger et al, 2007) Maintaining pressure and spontaneous breathing resulted in an increase in arterial oxygenation and helped prevent a deterioration in pulmonary gas exchange. (Putensen et al 2006) Studies have been carried out to determine whether high PEEP increases patients outcomes. These include the ALVEOLI study and the Lung Open Ventilation (LOV). These studies do not show an improvement on mortality with the increase in PEEP however show a decrease in days on the ventilator. (Mercat et al 2008) The patients right side was worse than the left on the CXR and auscultation. Therefore he was being positioned right side up and his back on pressure area cares. Repositioning patients not only protects the patients skin but it also improves gas exchange and decrease the risk of ventilator acquired pneumonia. (Deutschmann and Neligan, 2010) Positioning the patient with the good lung down may improve paO₂ and aid in the drainage of secretion. (Deutschmann and Neligan, 2010) Elevating the head of
The monitoring of expired carbon dioxide (CO2) concentration is becoming increasingly common in the operating room. As per American Society of Anesthesiologists (ASA) guidelines, continuous monitoring of end tidal CO2 (PETCO2) is recommended as standard II basics of anaesthetic monitoring especially to ensure adequate ventilation during all anaesthetics. In neurosurgical patients, intraoperative hypercapnia and hypocapnia must be detected reliably as the perfusion to brain and spinal cord varies with these values. Intermittent arterial blood gas (ABG) samples are routinely analysed to determine the partial pressure of carbon dioxide in the arterial blood (PaCO2) during neurosurgical procedures. PETCO2 can also be used as a guide to maintain PaCO2 to desired level during the surgery.
In accordance with our findings, haemodynamic shock, particularly with simultaneous hypoxaemia, would be considerable risk factors for both inadvertent arterial catheterization and delayed clinical diagnosis considering that urgent and stressful procedures of cannulation, and less pulsatile back flow of less oxygenated blood by the catheter, might be expected. Central venous cannulation under ultrasonic guidance would probably reduce these
BPD): Early complications (30 days postoperatively): 1- Anastomotic leakage with peritonitis (0.5-9 average ), 2- Acute gastric dilatation, 3- Roux limb obstruction, 4- Wound infection (sever 4.4% minor 11.4),

There is much deliberation concerning phenylephrine and vasopressin working on systolic blood pressure. Both constrict blood vessels, both can lead to bad complications if you give it into a blown IV and phenylephrine will cause pulmonary arterial vasoconstriction as well. Fluid resuscitation was continued while BP was supported with phenylephrine and vasopressin. Phenylephrine was changed
After surgery, Mr. Baker is taken to a room on the medical-surgical floor. He has an IV infusing at 125 ml/hr, a PCA pump, and a nasogastric tube connected to low suction. He is receiving oxygen through a nasal cannula.
Other postoperative findings include: Abnormally enlarged bronchial arteries. This may be due to decreased pulmonary blood flow and hypoplastic pulmonary artery. Next, the most common rhythm disturbances in this population include sinus bradycardia and atrial flutter that can contribute to late sudden cardiac death. These rhythm disturbances are thought to arise due to extensive intra-atrial sutures causing trauma to the sinus node and
Hypertension is presented as an increase in blood pressure. Blood pressure is the product of increased cardiac output and systemic vascular resistance. The risk factors are what attribute to the pathophysiology of postoperative hypertension. Hypercarbia causes an increase in catecholamine concentrations, which increases blood pressure. To decrease the risk of end organ damage and surgery complications associated with hypertension, therapy should be initiated in patients with systolic blood pressure above 180 mmHg or a diastolic blood pressure above 110 mmHg once the risk factors (pain, hypercarbia, and excitement on emergence of anesthesia) of postoperative hypertension have been treated. There are many complications and other underlying conditions may be associated with patients postoperatively and the medications chosen to initiate should be based on each individual patient. The ideal medication to treat postoperative hypertension has a quick onset and a short duration of
