Hi everyone!

I am currently a BSN student and my ultimate goal is to become a CRNA. I have to do a research paper and I would like to do it on something that is related to that field.

Does anyone know of any topics that I could research? Any help would be GREATLY appreciated!!

Post-Operative Nausea and Vomiting (PONV) is a huge topic in anesthesia, that has an impact on nursing as well. PONV is one of the most common unwanted side effects of anesthesia/drugs and has effects on patient satisfaction, length of hospital stay, post-op complications, etc.... So I think it would be a good topic in light of the fact that both RN's (in the PACU, ICU, etc...) and CRNA's deal with PONV on a regular basis. Hope this helps! Good luck to you!!!

That's interesting, thanks!

I was also looking at the use of beta blockers prophylactically in non-cardiac patients.

Any other suggestions?

Since no one took me up on it last year, I will offer it here....


I want to know whether keeping the endotracheal cuff pressure less than 30 cm H2O during surgery results in a decreased incidence of sore throat. Of course, you will have to control for ease of intubation, # of attempts, etc.

It appears that most Anesthesia practitioners inflate the balloon of the endotracheal tube by feel. Very few use a manometer, although this has long been the standard of care in ICU settings to prevent tracheal necrosis.

Intracuff pressure and tracheal morbidity: influence of filling with saline

BACKGROUND: Diffusion of nitrous oxide into the cuff of the endotracheal tube
results in an increase in cuff pressure. Excessive endotracheal tube cuff
pressure may impair tracheal mucosal perfusion and cause tracheal damage and
sore throat. Filling the cuff of the endotracheal tube with saline instead of
air prevents the increase in cuff pressure due to nitrous oxide diffusion. This
method was used to test whether tracheal morbidity is related to excess in
tracheal cuff pressure during balanced anesthesia. METHODS: Fifty patients with
American Society of Anesthesiologists physical status I or II were randomly
allocated to two groups with endotracheal tube cuffs initially inflated to 20-30
cm H(2)O with either air (group A) or saline (group S). Anesthesia was
maintained with isoflurane and nitrous oxide. At the time of extubation, a
fiberoptic examination of the trachea was performed by an independent observer,
and abnormalities of tracheal mucosa at the level of the cuff contact area were
scored. Patients assessed their symptoms (sore throat, dysphagia, and
hoarseness) at the time of discharge from the postanesthesia care unit and 24 h
after extubation on a 101-point numerical rating scale. RESULTS: Cuff pressure
increased gradually during anesthesia in group A but remained stable in group S.
The incidence of sore throat was greater in group A than in group S in the
postanesthesia care unit (76 vs. 20%) and 24 h after extubation (42 vs. 12%; P <
0.05). Tracheal lesions at time of extubation were seen in all patients of group
A and in eight patients (32%) of group S (P < 0.05). CONCLUSION: Excess in
endotracheal tube cuff pressure during balanced anesthesia due to nitrous oxide
diffusion into this closed gas space causes sore throat that is related to
tracheal mucosal erosion.

Sore throat after endotracheal intubation.

Nitrous oxide can diffuse into the cuff of an endotracheal tube during tracheal
intubation, and the cuff pressure against the tracheal wall may cause mucosal
damage. An endotracheal tube has been developed (Brandt Anesthesia Tube) that
effectively limits nitrous oxide-related intracuff pressure increases. We
determined whether the incidence of postoperative sore throat could be reduced
by using this tube. Forty-eight female patients, 18-50 yr of age, were included
in the study. Endotracheal intubation was performed with either a Brandt
Anesthesia Tube or a Mallinckrodt endotracheal tube. All patients were
interviewed postoperatively after 20-30 h by individuals who did not know which
tube was used. In the Mallinckrodt group, 12 of 20 patients had a sore throat
and 10 patients had intracuff pressures greater than 25 mm Hg. Only 3 of 20
patients in the Brandt group had a sore throat. We found that the incidence of
sore throats after intubation could be significantly reduced by using the Brandt
Anesthesia Tube (P less than 0.005).

Cuff pressure idea was best one - very small and specific, could be done. Forget the others - concepts way to broad and have been done over and over and over. Think of something small - using IM ephridrine for spinals in OB, efficacy of tilting OR table after spinals, etc.
