    ABSTRACT: The authors found no study to compare the efficacy of bolus dose fentanyl and remifentanil blunting the cardiovascular intubation response in children, so they designed this randomized, double-blind clinical study to assess the effects of remifentanil 2 microg/kg and fentanyl 2 microg/kg by bolus injection on the cardiovascular intubation response in healthy children. One hundred and two children, the American Society of Anesthesiologists (ASA) physical status 1-2 and scheduled for elective plastic surgery under general anesthesia, were randomly divided into one of two groups to receive the following treatments in a double blind manner: remifentanil 2 microg/kg (Group R) and fentanyl 2 microg/kg (Group F) when anesthesia was induced with propofol and vecuronium. The orotracheal intubation was performed using a direct laryngoscope. Blood pressure (BP) and heart rate (HR) were recorded before anesthesia induction (baseline values), immediately before intubation, at intubation and every minute for 5 minutes after intubation. The percent changes of systolic blood pressure (SBP) and HR relative to baseline values and the rate pressure product (RPP) at every observing point were calculated. The incidences of SBP and HR percent changes >30% of baseline values and RPP >22,000 during the observation were recorded. There were no significant differences between groups in the demographic data, baseline values of BP and HR and the intubation time. As compared to baseline values, BP, HR and RPP at intubation and their maximum values during observation increased significantly in Group F, but they all decreased significantly in Group R. BP, HR and RPP at all observed points, and their maximum values during the observation, were significantly different between groups. There were also significant differences between groups in the percent change of SBP and HR relative to baseline values at all observed points and their maximum percent changes during the observation. The incidences of SBP and HR percent increased >30% of the baseline values and RPP >22,000 during the observation, were significantly higher in Group F than in Group R, but the incidences of SBP and HR percent decreased >30% of baseline values were significantly lower in Group F compared with Group R. When used as part of routine anesthesia induction with propofol and vecuronium in children, fentanyl 2 microg/kg by bolus injection fails to effectively depress the cardiovascular intubation response. Remifentanil 2 microg/kg by bolus injection can completely abolish the cardiovascular intubation response, but also cause more adverse complications of temporary significant cardiovascular depression.

    ABSTRACT: To compare the cardiovascular responses to orotracheal or nasotracheal intubation with the aid of GlideScope video laryngoscope (GSVL). Sixty patients, American Society of Anesthesiologists (ASA) physical status I, aged 16-50 years, scheduled for elective plastic surgery under general anesthesia,were randomly allocated equally to the orotracheal intubation group (OTI group) and the nasotracheal intubation group (NTI group). After the routine anesthesia induction, orotracheal and nasotracheal intubation was respectively performed with the aid of GSVL. Non-invasive blood pressure and heart rate (HR) were recorded before (baseline values) and after anesthesia induction (postinduction values), during intubation and every minute for 5 minutes after intubation. Maximum values of blood pressure and HR during the observation periods were recorded. The product of HR and systolic blood pressure [rate pressure product (RPP)] at every time point was calculated. Duration for glottis exposure and duration for successful intubation were also noted. There were no significant differences between two groups in the demographic data (P>0.05). Glottis exposure time and intubation time in NTI group were significantly longer than those in OTI group [(52.2+/-13.5) seconds vs. (40.5+/-15.2) seconds, P<0.05]. After anesthesia induction, blood pressure and RPP in both groups decreased significantly compared with baseline values, but no significant change in HR was noted. Compared with their postinduction values, the blood pressure and RPP in both groups and HR in OTI group increased significantly at intubation. In OTI group,the maximum values of HR, diastolic blood pressure (DBP), mean arterial pressure (MAP), RPP exceeded their baseline values. But in NTI group,only maximal HR during the observation period was significantly higher than the baseline values. The blood pressure at every time point was not significantly different between two groups. But intubation in OTI group caused significant increases in HR and RPP compared with those in NTI group (both P<0.05). In anesthetized adult patients, orotracheal and nasotracheal intubations with the GSVL can result in a similar pressor response, however orotracheal intubation with GSVL causes more marked cardiovascular responses than nasotracheal intubation with the aid of GSVL.

    ABSTRACT: The GlideScope videolaryngoscope (GSVL) has been shown to have no special advantage over the Macintosh direct laryngoscope (MDL) in attenuating the circulatory responses to orotracheal intubation, but no study has compared the circulatory responses to nasotracheal intubation (NTI) using the two devices. This prospective randomized clinical study was designed to determine whether there was a clinically relevant difference between the circulatory responses to NTI with the GSVL and the MDL. Seventy-six adult patients were randomly allocated equally to the GSVL group and the MDL group. After induction of anesthesia, NTI was performed. Non-invasive blood pressure (BP) and heart rate (HR) were recorded before induction (baseline values) and immediately before intubation (post-induction values), at intubation and every minute for a further five minutes. During the observation, times required to reach the maximum values of systolic BP (SBP) and HR, times required for recovery of SBP and HR to postinduction values and incidence of SBP and HR percent changes > 30% of baseline values were also noted. The product of HR and systolic BP, i.e. rate pressure product (RPP), and the areas under SBP and HR vs. time curves (AUC(SBP) and AUC(HR)) were calculated. The NTI with the GSVL resulted in significant increases in BP, HR and RPP compared to postinduction values, but these circulatory changes did not exceed baseline values. BPs at all measuring points, AUC(SBP), maximum values of BP and incidence of SBP percent increase > 30% of baseline value during the observation did not differ significantly between groups. However, HR and RPP at intubation and their maximum values, AUC(HR) and incidence of HR percent increase > 30% of baseline value were significantly higher in the MDL group than in the GSVL group. Times required for recovery of SBP and HR to postinduction values were significantly longer in the MDL group than in the GSVL group. The pressor response to NTI with the GSVL and the MDL was similar, but the tachycardiac response to NTI was lesser and of a shorter duration when using a GSVL than when using an MDL.
