—Effects of drugs administered during anesthesia on cerebrospinal vessels—Hiroki Iida2008 Volume 27 Issue 2 Pages 106-117

JOURNAL FREE ACCESSTo understand the characteristics of reactivity of the cerebrospinal vessels is helpful in maintaining appropriate circulation in the central nervous system. In addition, it is useful to know that ischemia-reperfusion, disruption of blood- brain (spinal cold) -barrier, or hypothermia could potentially modify the influences on cerebrospinal circulation and reactivity induced by vasoactive drugs administered during anesthesia.For anesthesiologists it is perceived to be important to use the anesthetic and anesthesia-related agents under full understanding their effects on cerebrospinal vessels for preventing exacerbation of the damage in the central nervous system.View full abstractDownload PDF (1021K) -

JOURNAL FREE ACCESSChanges in temperature influence cardiac lusitropic function, and hypothermia prolongs the relaxation process and hyperthermia shortens it. The goodness of halflogistic (hL) function curve-fits for the isovolumic relaxation left ventricular (LV) curves from the minimum of the first time derivative of LV pressure (dP/dtmin) observed at different temperatures are superior to the goodness of conventional mono-exponential (mE) function curve-fits, as the correlation coefficients are larger and residual mean squares are smaller for hL functions than mE functions at any temperature. The hL time constant (PτL) is dependent on temperature as is the mE time constant (PτE), and PτL could be a more precise lusitropic index than PτE. PτE is overestimated in hypothermia and underestimated in hyperthermia. It is suggested that PτL decays with increasing temperature and decreasing dP/dtmin as is characteristics of the hL function curve. The temperature coefficient (Q10) value of the reciprocal of PτL is 2.2. The hL function is a more useful model than the mE function for evaluating lusitropism of the isovolumic relaxation LV curve and PτL is a more reliable relaxation time constant than PτE regardless of temperature.View full abstractDownload PDF (1213K) -

JOURNAL FREE ACCESSCritical events during anesthetic management from January 2004 to December 2006 in Shizuoka Children's Hospital, were analyzed retrospectively. The overall incidence was 4.94/10, 000 and comparable to the result from the report of committee on operating room safety of Japanese Society of Anesthesiologists.
Seven cases were concluded to be critical events. Four of them were suffered with cardiac arrest and required cardiopulmonary resuscitation and the other three cases were judged to be life threatening by us but recovered without cardiopulmonary resuscitation. Four of those accidents were happened in the operating rooms and the remaining all 3 events were in the cardiac catheterization laboratory. The incidence of critical events during cardiac catheterization was significantly higher than that in operating rooms. The cause might be attributed to inadequate equipments, drugs, the remoteness from operating rooms and undertrained nursing staffs for cardiopulmonary resuscitation. As a conclusion, we insist that cardiac catheterization laboratory should be inside or as near the operating rooms as possible to cope with unpredictable critical events immediately during anesthesia.View full abstractDownload PDF (599K) -

JOURNAL FREE ACCESSWe retrospectively examined 17 consecutive patients with acute ischemic stroke, who were admitted within three hours after onset and received intravenous recombinant tissue plasminogen activator (IV rt-PA) therapy. The first patient, who received MRI with perfusionweighted image (PWI) / diffusion-weighted image (DW I) mismatch, had an interval of 90 minutes between admission and the start of IV rt-PA therapy. Since evaluation by PWI/DWI mismatch is timeconsuming, we have developed a management protocol for acute stroke patients, who routinely underwent MRI (DWI and intracranial MR angiography) but not PWI. The mean interval between admission and the start of the IV rt-PA did not significantly differ between patients with and without MRI.Eight patients (47%) were good recovery, five (29%) were moderately disabled, three (18%) were severely disabled, and two (6%) died within 30 days after admission. MRI is essential for performing IV rt-PA therapy safely with detecting early ischemic change and main trunk occlusion.View full abstractDownload PDF (4975K) -

JOURNAL FREE ACCESSWe describe a patient who showed hyperglycemia and shock during rehabilitation after traumatic head injury followed by severe brain damage and death. The cardiovascular collapse was developed in hyperglycemic state, which might exacerbate acute neurological damage, finally followed by neurological diabetes insipidus and brain death.View full abstractDownload PDF (334K) -
