The carotid pulse check revisited: What if there is no pulse?
2000
This study was undertaken to evaluate the diagnostic accuracy and time required by first responders to assess the carotid pulse in potentially pulseless patients. We conducted a prospective, randomized study of first responders (n = 206; four different training levels) and were blinded as to the patients' conditions in the cardiac operating rooms of a university hospital. Sixteen patients underwent coronary artery bypass surgery on nonpulsatile cardiopulmonary bypasses. Carotid pulse check was performed either during pulsatile (spontaneous) or during nonpulsatile (extracorporeal) circulation. Patients' hemodynamic status at the time of assessment, diagnostic accuracy of the first responders…
Postoperative nausea and vomiting in patients after craniotomy: incidence and risk factors
2011
Object The purpose of this study was to assess the incidence and risk factors of postoperative nausea and vomiting (PONV) after craniotomy because most available data about PONV in neurosurgical patients are retrospective in nature or derive from small prospective studies. Methods Postoperative nausea and vomiting was prospectively assessed within 24 hours after surgery in 229 patients requiring supratentorial or infratentorial craniotomy. To rule out the relevance of the neurosurgical procedure itself to the development of PONV, the observed incidence of vomiting was compared with the rate of vomiting predicted with a surgery-independent risk score (Apfel postoperative vomiting score). Re…
Prospective assessment of postoperative pain after craniotomy.
2010
Pain after craniotomy may be underdiagnosed, despite the fact that it can increase postoperative complications for example arterial hypertension and postoperative hemorrhage. This study investigates the incidence and intensity of pain after craniotomy and characterizes the influencing parameters. During a 1-year period 256 patients undergoing elective craniotomy were prospectively included in the study. Intensity of pain was evaluated 1, 4, and 24 hours after extubation using a verbal numerical rating scale (NRS) ranging from 0 (no pain) to 10 (maximal pain). Routine perioperative pain management was not influenced by the investigators. Parameters including patient-related factors, drug adm…
Orthotopic liver transplantation in a malignant hyperthermia susceptible patient.
2005
We present a patient with hepatitis C and D and hepatocellular carcinoma who underwent preoperative evaluation for orthotopic liver transplantation. In his past medical history, he reported a life-threatening event during tonsillectomy in 1975. Intubation was impossible due to extreme jaw muscle tension, followed by excessive elevation in body temperature, tachycardia, and coma for a few days. We evaluated him for malignant hyperthermia, according to the European Malignant Hyperthermia Group Protocol, and found him highly positive in both the halothane and caffeine test, respectively. Three months later, we performed an orthotopic liver transplantation. During retransplantation 4 years late…
